5 Signs I Thought Were Just “Menopause”… But Were Actually My Nervous System Breaking Down. And This Is What Finally Helped Me.
Okay so I have been putting off writing this one for a while. Not because I do not want to share it. Because I kept trying to figure out how much of it to share and I kept landing on: all of it. Which is slightly terrifying but also I am 47 and I have stopped having the energy to be precious about things that might help someone.
So. All of it.
In March of 2023 I sat in my GP’s office and described what had been happening to my body for the previous eight months and she listened and nodded and said the word perimenopause and then said something about how symptoms varied enormously between women and that we could look at HRT if things became unmanageable.
I drove home and cried in the car park of Boots for about ten minutes. Not because the diagnosis was bad news. Because I had just described five different things going wrong simultaneously and been given one word that covered all of them without explaining any of them. I had the very specific feeling of having gone somewhere for an answer and come back with a label instead.
It took me two more years to find out what was actually happening. And when I did, the first thing I felt was not relief. It was fury. Because it was not complicated. And nobody had told me.
Sign#1
The Anxiety That Had No Reason to Be There
I need to be specific about this because anxiety is one of those words that covers too much ground. I was not having panic attacks. I was not unable to function. What I had was a permanent low-frequency hum underneath everything. A background static of dread that was just always present. Not about anything specific. Not triggered by anything I could point to. Just there, sitting underneath every ordinary Tuesday like something bad was about to happen even when nothing was.
I had never been like this before. I was the person in a crisis who stayed calm. The anxiety was not my personality — it was new, and it had arrived quietly enough that I had half-convinced myself it was just a reasonable response to being a woman in her mid-forties with a full life and a lot to think about.
My husband noticed before I admitted it. He said I seemed braced. Like I was always waiting for something. He was right. I just did not know what.
Here is the thing nobody told me and that I want you to actually understand rather than just read past.
Think of oestrogen as a phone signal. And the vagus nerve — the nerve that runs from your brain down through your neck and into your gut — as the phone itself. All the apps on the phone: your anxiety regulation, your sleep, your temperature control, your hair follicle health. They all depend on that signal to work properly.
When oestrogen starts declining, the signal drops.
The anxiety that appeared from nowhere was not anxiety. It was five bars dropping to one. My nervous system had lost the thing that was keeping it calibrated. Not a mental health problem. A signal problem. And nobody thought to say that out loud.
The 3am Wake-Up That Had Never Existed Before in My Life
I have been a good sleeper since I was a child. I fell asleep fine. Always have. Within ten minutes of lying down, reliably, for forty-six years.
What started happening in the second year of perimenopause was specific and consistent and maddening. I would fall asleep at 10:30. Then at some point between 2:30 and 3:30, without any external trigger, I would be completely awake. Not groggy. Awake. Heart slightly elevated. Mind already running through tomorrow’s schedule, last week’s conversation, the email I forgot to send, something I said in 2019 that nobody remembers but me.
Every. Single. Night.
I tried melatonin. Started at 1mg, worked my way up to 10mg over six months. It helped me fall asleep faster and did absolutely nothing for the 3am thing. I tried magnesium. L-theanine. The Huberman protocol. Mouth tape, which my husband found so funny he used a photo of me wearing it as his phone wallpaper for four months. My husband slept through all of it. Every night he lay six inches away from me, completely at peace. There is a specific loneliness in being awake at 3am next to someone who is not. I know that now.
What I now know: Melatonin is aimed at helping you fall asleep. That is its one job. It works at the beginning of the night and then it is finished.
What was waking me up at 3am was happening in a completely different part of the night and a completely different system. When the signal drops, your body cannot properly suppress the cortisol rise that naturally starts in the early morning hours. Cortisol goes up too early. Your body decides the night is over. You wake up at 3am feeling immediately alert because as far as your nervous system is concerned, it is morning.
Melatonin cannot fix that. Not at 1mg, not at 10mg. I was putting fuel in the wrong tank for eight months.
I want to tell you about the pillow because I think about it a lot.
I started flipping it over every morning so I did not have to see the hair on it. This became so automatic that I did not notice I was doing it for about a month, until one morning my daughter came into our room early for something and I caught myself flipping it and realised I did not want her to see. Not because it was shameful. Because I had not told anyone how bad it had gotten and seeing it through her eyes suddenly made it real in a way it had not quite been when it was just between me and the pillow.
The shower drain I have mentally filed under Things I Will Process Later. My husband unclogged it once without saying anything and I wanted to hug him and also never speak of it again. We have not spoken of it.
My dermatologist was lovely. She said telogen effluvium, stress-related, manage your stress, give it time. She was right about the type. She was not completely right about the cause. Because I had been through genuinely stressful periods before without losing hair like this, and nobody could tell me why this time was different.
What I eventually understood:
When the signal drops and your nervous system goes into permanent low-level stress mode, your body starts making decisions about what is essential and what is not. Your heart: essential. Your lungs: essential. Your hair follicles: not essential for survival. So blood flow gets redirected. The follicles start getting less of what they need. They go into their resting phase early and stay there.
I was treating my scalp. The problem was not in my scalp. The problem was that my body had deprioritised my scalp because the signal was down and my nervous system thought we were in a permanent low-grade emergency. No serum fixes that. You have to reach the signal.
The one I think about most happened at my birthday dinner in November.
My husband had organised it, taken the kids somewhere, the whole thing. It was a good evening. And then in the middle of the main course I felt it start — that building heat from nowhere, moving up through my chest and neck and face while I sat there trying to hold a conversation and not look like I was spontaneously combusting.
I excused myself to the bathroom. Stood over the sink with cold water on my wrists. Looked at myself in the mirror. I was 47 years old at my own birthday dinner having a hot flash in a restaurant bathroom and I did not understand why they were coming with the frequency and the randomness that they were. I had started tracking them. I had a spreadsheet. The spreadsheet made no sense.
Here is why they were random:
The vagus nerve — the same dropped signal — is involved in how your body monitors and regulates its own temperature. When the signal is strong the communication is accurate. When the signal drops the communication becomes erratic. Your body calls for a cooling response when no cooling is needed. The flash is not just oestrogen dropping. It is your nervous system’s thermostat losing its calibration because the signal that was keeping it accurate is gone.
The spreadsheet made no sense because I was looking for patterns in the symptom when the cause was the same as everything else. Same nerve. Same dropped signal. Showing up somewhere different.
Five symptoms. Five different partial explanations. One cause that nobody connected for me in two years of looking. I find this equal parts fascinating and enraging.
This was the one that frightened me most. Not the anxiety, not the hair, not even the 3am thing. The exhaustion.
Because I was sleeping. Seven, sometimes eight hours. And I was waking up depleted in a way that had nothing to do with how many hours I had been in bed. Not groggy. Not sleepy. Depleted. The specific deep-cellular exhaustion of a body that had not actually rested even though it was unconscious for eight hours.
Every blood test was normal. Thyroid fine. Iron fine. B12 fine. My GP said I looked tired and asked about my stress levels. I said they were manageable. She nodded. I started wondering if I was depressed. I did not think I was but I could not explain the exhaustion any other way.
What was actually happening:
The number of hours you spend in bed and the quality of what happens during those hours are not the same thing. When the signal is down, your nervous system cannot fully shift into recovery mode during sleep. It stays in a low hum of alert even while you are unconscious. Not enough to wake you. Enough to prevent the deep restorative stages where your body actually repairs itself.
It was like trying to fill a bath with the plug out. More water was not going to help. I needed to stop the drain. Which meant reaching the signal.
By the time I connected all five of these signs I had been living with them for the better part of two years. Four doctors. More supplements than I want to add up the cost of. Every protocol I could find. Some of it helped a little. None of it changed the underlying pattern. Because none of it reached the underlying pattern.
The underlying pattern was a vagus nerve running on a dropped signal. And the vagus nerve is not something you can address with a supplement or a breathing app or a sleep hygiene checklist. You have to actually stimulate it.
Someone in a perimenopause Facebook group posted a link and wrote absolutely nothing except: this one is different.
I almost scrolled past it. I was so tired of clicking on things.
But it was 11pm and I could not sleep and I had nothing to lose by reading.
The article explained all of this. The signal. The nerve. Why five separate symptoms were actually one problem showing up in five different places. And then it said something I had not considered. That you can send the signal directly. You do not have to wait for the oestrogen to come back. You do not have to meditate for forty minutes every day or stand under a cold shower at 6am. Those things work. I was never going to do them consistently. Because I am a real person with a real life and I have tried to maintain practices before.
Everything I had tried before worked from the outside in. The supplements addressed individual symptoms. The protocols required a consistency I could not maintain. None of them changed what my nervous system was doing on its own.
Novu works differently. You put a small device on your neck for four minutes and it delivers a gentle pulse directly to the vagus nerve. Not dramatic. At the lowest intensity I barely felt it. At the intensity I use now it is a mild tingling and then four minutes later it is done. Same mechanism as the breathing exercises and cold exposure that naturally activate the nerve — but delivered directly, consistently, without requiring anything from me except four minutes.
I am aware this sounds like something I would have scrolled past three months earlier. But I ordered it at midnight because the article had just explained two years of my life to me, and the 30-day money-back guarantee meant that if it did not work I would lose nothing except four minutes a night.

What Happened When I Finally Reached the Signal
I used Novu for the first time on a Wednesday evening. Sat on the edge of my bed, four minutes. I felt something shift that I do not have precise language for. Not dramatic. More like something that had been slightly wrong for a long time becoming slightly less wrong. The background static turned down a notch.
I slept through to 5:50am that night. I cannot tell you the last time that had happened.
My husband asked what I had changed on the Saturday. He said I seemed different. Less braced, was the word he used. Same word my daughter had used eight months earlier. Different context.
Three weeks later the 3am thing was mostly gone. The anxiety had a different quality — it came and went rather than sitting permanently underneath everything. The hair situation had visibly improved. The exhaustion that sleep was not fixing was starting to be fixed by sleep.
I flipped the pillow back over last month. The right side up.
Being honest about what this is and is not.
Novu is not a menopause treatment. It does not replace the conversation you should be having with your doctor about your hormones. If you are on HRT or considering it, that is a completely separate and valid decision and Novu sits alongside it, not instead of it. What it addresses is the nervous system layer — the vagal tone that oestrogen was supporting. The 30-day guarantee means you can find out whether that is your missing piece without any financial risk.
I know what you might be thinking. You have tried things. You have been the person who orders at midnight and tries things. And some of them helped a little and then stopped helping and you went back to wherever you were before.
I am not going to tell you this is the thing that will work for you. What I can tell you is that the 30-day money-back guarantee is real and unconditional. You do not lose money finding out. You lose four minutes a night for thirty days and then you either have an answer or you have a full refund.
If you have been explaining away five separate symptoms for longer than you should have — do not wait as long as I did.
