I Haven't Slept Through the Night Since I Was 46. Last Month, at 49, I Did. Here's What Changed and What Didn't.

I know what 3am looks like.

I know it from above — lying on my back, staring at the ceiling with the particular clarity that only arrives when you desperately need to be unconscious. I know it from the side — turned toward the window, watching the dark become slowly, unhelpfully lighter. I know it from my phone screen, which I told myself I wouldn't check and always checked. 3:07. 3:22. 3:41.

I would fall asleep at ten. Sometimes ten-thirty if I pushed it. Completely, genuinely exhausted — the kind of tired that should have made sleep easy, automatic, deserved. And then I would wake at 3am as if something had switched on inside me. Not groggy. Wired. My brain cycling through every unresolved thought, every unanswered email, every decision I hadn't made yet. Wide awake in a way that felt like cruelty.

I would lie there until 5:30. Then 6. Then whatever version of myself was possible on two hours of real sleep would get up, make coffee, and start again.

Every day. For months. Then years.

I adapted. I moved meetings. I cancelled evenings. I called it managing my schedule.

I ran a twelve-person business. I had meetings at 8am. I had a husband and two children and a mortgage and a diary that did not have space for a person who could not sleep. I adapted. I moved calls to the morning when I was sharpest. I started cancelling evening things. I stopped committing to anything I'd need to be bright for after 4pm. I called it "managing my schedule." I was managing my collapse.

The doctor told me I was stressed. I told her I'd been stressed at 35 and 40 and I had slept fine. She looked at me the way doctors look at women my age when they're about to say something that means nothing has to change for them. She suggested I try cutting back on caffeine.

I had already cut back on caffeine. I had already cut back on screen time and alcohol and late dinners and everything else the articles recommend. I had a sleep hygiene routine. I had blackout curtains. I had a magnesium supplement on my bedside table that I took every night because six different things online told me to. The magnesium did nothing except give me something to hope for while the clock showed 3am.

She eventually gave me sleeping pills. They worked for about ten days and then stopped working in the specific way that things that stop working do — where you lie there waiting for the effect that used to come and eventually realise it isn't coming tonight either.

I am not a person who gives up easily. I have built a business through things that should not have worked. I am a problem-solver by nature and this was a problem and I was determined to solve it.

I tried progesterone cream. I tried maca root. I tried ashwagandha. I tried melatonin at three different doses, and then read that melatonin doesn't actually help with this particular kind of sleep disruption and stopped. I found a private women's health clinic that agreed to try me on low-dose HRT. That helped with the hot flushes and steadied my mood in ways I hadn't noticed needed steadying. But I was still waking at 3am. Still running on reserve. Still not sleeping the way I had slept for the first forty-six years of my life.

The most exhausting thing was the performing. Nobody could see what was happening inside.

The most exhausting thing about it — and this is what nobody tells you — was the performing. Because I looked fine. I was still producing. I was still turning up to meetings and delivering and billing the same. Nobody could see what was happening inside. Internally I was running on emergency reserves that I knew were finite. My business partner started noticing something was off. My husband noticed I'd stopped laughing at things. I hadn't noticed that myself until he said it. That was the moment that stayed with me. I had become someone who didn't laugh at things, and I hadn't even known.

The next three years happened to me rather than with me.

I want to write that sentence again, because it's the most accurate description I have of what chronic sleep deprivation actually costs. It doesn't just take your rest. It takes your presence. You are physically in the room and functionally somewhere else, running a thin simulation of yourself while the real version waits for sleep that doesn't come.

I found my way to the answer the way most women find things: through someone else who had already been there.

A woman I know from a business network mentioned in passing that she'd tried a NAD+ injection protocol for her perimenopause symptoms and that sleep had been the first thing to change. I almost didn't ask her to elaborate. I had been let down by enough things that I had developed a reflex against hoping. But she was specific in the way that rang true. She didn't say "I have so much energy now." She said "I stopped waking at 3am. It took about four weeks. And then I just... didn't."

I went home and looked into it properly.

NAD+ — nicotinamide adenine dinucleotide — is a molecule that every cell in your body depends on. It is involved in energy production, DNA repair, and the regulation of the biological processes that keep your system functioning. What most people don't know is that after forty, NAD+ levels decline significantly — and that this decline is connected to many of the symptoms that get filed under "perimenopause" or "just getting older" and left there.

Sleep is not just a behaviour. It is a cellular process. The body's ability to regulate its circadian cycle, manage the hormonal transitions of the night, and restore the nervous system during sleep all depend on adequate cellular energy. When NAD+ levels fall below a functional threshold, those processes don't work the way they should. The 3am wake isn't random. It is the body failing to complete a restorative process that used to happen automatically.

The reason the supplements I tried didn't address this is that they weren't targeting the right thing. Magnesium supports sleep architecture, which is real and worth addressing — but it cannot compensate for a cellular energy deficit. HRT addresses the hormonal layer of perimenopause, which is also real and also worth addressing. Neither of them replenishes what your cells actually need to run the machinery of sleep.

The injection format matters because it bypasses the barriers that most supplements can't get past. When you swallow a capsule, the active compounds must survive digestion, navigate the conversion process in the gut, and arrive at the cell in a form it can actually use. For NAD+ precursors specifically, those losses are significant — and they compound as we age, because the gut's conversion capacity declines at the same time as demand increases.

Subcutaneous injection delivers the molecule directly into systemic circulation. No conversion chain. No gut degradation. The same mechanism used by millions of people daily for pharmaceutical management — and by a growing number of women in their forties and fifties who have run out of patience with formats that produce marginal results.

I started the NADPure protocol with the particular scepticism of someone who has been let down before. I did not tell myself it was going to work. I told myself I was trying one more thing.

The first two weeks I noticed nothing. The third week I noticed that I was waking at 3am less consistently. Not gone — less. Once I would have dismissed that. After three years, I measured it.

By week five I was sleeping through most nights. Not perfectly, not every night. But most nights. I was waking at 6am instead of 3am and the difference — the actual, physical difference in how I moved through the following day — was not subtle.

I stopped recording my meetings. I started writing fewer things on my list that should have been automatic. I noticed, one evening at dinner, that I was laughing at something my husband said. He noticed too. Neither of us mentioned it directly. We didn't need to.

NADPure is the protocol I ended up on. It is a subcutaneous injection pen for at-home use, shipped as high-purity NAD+ powder and activated at point of use. Each pen contains a pre-measured 500mg dose. Every production batch is independently laboratory tested — the results are available, not hidden behind a badge on a FAQ page. Ships with a silicone cool-pack. No refrigeration required on receipt. The compound stays in powder form until you mix it — which takes about 30 seconds — ensuring you are injecting fresh-activated NAD+, not a solution that has been sitting in transit for weeks.

There is no capsule. There is no conversion question. There is no wondering whether the active ingredient survived the journey from the label to your cell.

The pen is administered to abdominal tissue, the same site diabetics use for daily insulin management. The needle is fine-gauge. Most people describe a mild sensation and that's the entire event. It takes less time than making the magnesium tea I used to prepare every night for three years.

I want to be careful about what I say here because I am not a doctor and I know what it feels like to read something that promises too much. So I will say only what is true for me. I sleep now. Not perfectly. Not guaranteed. But consistently, genuinely, in a way I had stopped expecting to be possible.

I look well. I feel well. I sleep well.

After three years of lying awake at 3am staring at the ceiling, that is not a small thing.
