“I’m an Endocrinologist. And I’m Embarrassed by How Badly We’ve Failed Women Over 45 on Sleep.”

It starts the same way for almost every woman.

3:07am. Or 3:14am. Or 3:22am. The exact time barely matters — the experience is always the same. You wake up. Not slowly, not gently. Like a switch was thrown. Overheated. Heart going a little faster than it should. Body tired. Mind fully, uselessly, awake.

You lie there. You wait. Maybe you check your phone. Maybe you run through tomorrow’s list. Maybe you breathe, or count, or try every trick you know to get your nervous system to do the one thing it used to do automatically — settle back down.

It doesn’t settle. Not for hours. Not the way it used to.

My name is Dr. Rachel Brennan. I am 54 years old, board-certified in endocrinology, and for the first 22 years of my career, when a patient sat across from me and described exactly what I just described to you, I gave her the wrong answer.

I want to tell you what I should have said instead.

The complaint I heard a thousand times before I understood it

In medical training, you learn about insomnia in tidy categories. Sleep onset insomnia. Sleep maintenance insomnia. Early morning awakening. You learn the textbook causes: stress, depression, caffeine, anxiety, poor sleep hygiene. And you learn the textbook tools.

What you do not learn, in any meaningful depth — even in an endocrinology fellowship — is what actually happens to a woman’s sleep architecture when her estrogen and progesterone start to fluctuate in her mid-40s.

It’s barely a lecture. It’s a paragraph.

So for years, when a patient came in and said something like:

“Dr. Brennan, I fall asleep fine. But I wake up around 3am, completely soaked, heart racing, and I cannot get back to sleep no matter what I do. I’m exhausted. I’m forgetting things. I don’t feel like myself.”

I gave her the standard answers. Cut caffeine after noon. Limit screens. Keep the bedroom cool. Try magnesium. Have you considered melatonin?

Then she’d come back six months later and tell me, politely, that none of it worked.

I would write “sleep disturbance, perimenopausal” in her chart and move on to the next patient.

I did not understand, at the time, what I was actually being told.

Then it happened to me

The clock that ended a year of my life. Every night, like a switch being thrown.

In the spring of 2024, just after my 52nd birthday, I started waking up at 3am.

Not occasionally. Every single night.

I would fall asleep without trouble around 10:30. Then, around 3:00 to 3:15, like clockwork, I’d come up out of sleep already overheated, already alert, already running tomorrow’s clinic schedule in my head. My pajamas were damp. My heart felt like it was in a slightly higher gear than it should have been. And the cruelest part: my body was profoundly tired. But my brain was online. Fully lit. Ready to argue.

I’d lie there until 5:30 and drag myself into the shower already losing the day.

I was, by any honest measure, the worst version of myself I had ever been. Short with my staff. Forgetting things I had no business forgetting. I caught a small charting error on a patient I’d been seeing for ten years — nothing dangerous, but the kind of slip I would never have made five years ago — and I sat in my office and stared at it for a long time.

So I did exactly what I had been telling my patients to do for twenty years.

I cut caffeine after noon. Bought blackout curtains. Went to bed earlier. Tried magnesium. Tried melatonin — 3mg first, then 1mg when the 3mg gave me vivid, exhausting dreams. Tried valerian tea. Tried mindfulness apps. Tried, briefly, a low-dose prescription sleep aid I wrote myself, and quietly stopped after four nights because I did not like who I was at 9am.

None of it fixed the 3am wake-up.

Some of it made the mornings worse.

And that is when I had the uncomfortable realization that I think every physician over 50 eventually reaches: the advice I have been giving these women for twenty years is aimed at the wrong moment of the night.

What I started to understand

Here is what nobody emphasized strongly enough in my training, and what I now tell every patient who will listen:

Falling asleep and staying asleep are two entirely different problems. They have different drivers. And they almost certainly need different support.

Almost everything in the pharmacy sleep aisle — almost every gummy, almost every supplement labeled “sleep” — is built around one job: helping a person who can’t fall asleep at bedtime get drowsy.

That is not the menopausal woman’s problem.

Her problem is what happens four to five hours into the night. When the body’s overnight hormonal environment shifts. When core temperature spikes. When the nervous system goes from “rest” to “alert” in the span of about ninety seconds — and when the part of the brain responsible for settling back down has changed.

It was not anxiety. It was not a character flaw. It was not something a better bedtime routine was going to fix.

It was a physiology problem. And it needed a physiology answer.

Why it took medicine so long to say this out loud

For decades, almost all meaningful sleep research was done on men, or on younger women. Menopausal sleep — the specific, grinding disruption that begins in perimenopause and can stretch well into the postmenopausal years — was a footnote in the literature. Not a subject.

A 12-minute appointment cannot hold this problem. When a woman in her 50s comes in describing fatigue, brain fog, night sweats, and a 3am wake-up that has persisted for two years, it is genuinely difficult to untangle what is hormonal, what is psychological, what is lifestyle. So we reach for the thing we can answer quickly.

And the part that stings most: the pharmaceutical tools we have for sleep were never built for this. They were built for acute insomnia. Not for the slow, cyclical, hormone-linked disruption that begins in perimenopause. So women get handed the wrong tool, report back that it didn’t work, and are quietly filed under “difficult to treat.”

I did this for over two decades. And I am sorry.

Dr. Brennan in clinic. “I had been giving the wrong advice for twenty years. I didn’t know it until it happened to me.”

What I started looking for

Once I understood the actual problem, I started looking — for myself and for my patients — for something very specific.

Without melatonin. I had watched too many women describe the morning fog, the vivid dreams, the “wading through wet cement” feeling that comes with chronic melatonin use. For something aimed at making women functional the next day, that is not an acceptable trade.

Without hormones. For many women — including those with a family history of certain cancers — adding phytoestrogens or black cohosh on top of an already-shifting hormonal environment is not the right call. That is the endocrinologist in me speaking.

Non-habit forming. The women in my practice want support, not dependency.

Built specifically for this stage of life. Not a generic sleep product with a pink label.

For about six months, I couldn’t find it. Then a colleague — a women’s health nurse practitioner I’ve worked alongside for eight years — mentioned, almost in passing, a small brand she had been quietly recommending to her own patients. Not pushing. Not selling. Mentioning, with the particular restraint that healthcare workers use when something is actually working.

The brand was called Sloom.

Sloom. The first formula in this category I could defend to a colleague without wincing.

Why it earned a second look

My first reaction when she said “gummy” was a wince. I have a very low tolerance for wellness theater. So I asked her to send me the label.

What I read was, frankly, the first thing in a long time that made me sit up straighter.

There was no melatonin in the formula. Not a hidden microdose. Not a “proprietary blend” sleight of hand. None.

There were no hormones, no phytoestrogens, no black cohosh, no soy isoflavones — nothing an endocrinologist would have to think twice about handing a patient with a complicated history.

And what was in it was, ingredient by ingredient, a list I could defend out loud:

• Magnesium glycinate — a form of magnesium I’ve recommended for years. Well absorbed, gentle on the gut, with a solid evidence base for supporting relaxation and sleep quality.
• L-theanine — an amino acid that supports a calmer mental state without sedation. One of the most underrated ingredients in this category.
• Passionflower — long history of traditional use for nighttime calm.
• Valerian root — one of the few botanicals studied specifically for sleep continuity, not just sleep onset. For the menopausal woman, that distinction is everything.

It was the cleanest formula I had seen aimed at this stage of life. I ordered a bottle.

What I noticed as a patient — not as a physician

The morning I woke to my alarm without seeing the clock once. I sat on the edge of the bed and just breathed.

The first night, I woke at 3:08am — same as always. But something was different. I was awake, but I was not alert.

There is a real physiological difference between those two states. Alert is what I’d been experiencing for close to a year: heart elevated, mind racing, body braced. Awake-but-not-alert is the version of waking we all used to have — where you stir, register that you’re conscious, roll over, and slide back under.

I rolled over. I slid back under. I woke to my alarm at 6:15.

By week two, I was sleeping through four nights in seven. By week four, I had gone eleven consecutive nights without a significant wake-up. I called my colleague from the car park and told her, in a slightly embarrassing way, that I owed her something.

By month two, my husband told me I seemed less “braced.” His word, not mine. But it was the most accurate single word anyone had used to describe what the previous year had done to me — and what was finally lifting.

By month three, I was recommending Sloom to patients. By month four, I had personally sent it to eleven women I care about, including my sister.

In a follow-up of the first 47 patients in my practice who tried it, 39 reported fewer 3am wake-ups within the first month. That is not a clinical trial. But for a physician trying to help real women in her actual practice, it is a number that matters.

What I now tell every woman who walks in with this complaint

1. One. This is a menopause-pattern sleep problem, not generic insomnia. You are not broken. You need support built for the actual moment of the night you are struggling with.
2. Two. Falling asleep and staying asleep are different problems. Almost everything you have tried was built for the first one. Sloom is built for the second one.
3. Three. You do not need to be sedated to sleep better. The goal is a calmer night and a clearer morning.
4. Four. Be patient. Give it at least three weeks. Sleep is a system. Systems do not turn around in one night.
5. Five. If you have a serious underlying medical condition, are pregnant or nursing, or are on prescription sleep medication, please speak with your own physician first.

The part I want you to actually hear

I’m going to step out of my professional voice for one paragraph, because I think it is the only part of this article that truly matters.

I spent a year of my own life sitting on the edge of the bed at 3:47am thinking this is who I am now. And I was wrong. I was not who I had become because something was broken in me. I was who I had become because I had stopped sleeping the way my body needed to sleep, and nobody — including me — had figured out the right tools yet.

You are not who you have become over these last twelve or twenty-four or thirty-six months of bad nights. That woman is still there. She is exhausted. She is fed up. She is, some mornings, angry in a way she can’t even name. But she is there — and she will come back the moment her body gets the right support for the moment of the night that has been stealing from her.

I hope you find her again.

Sincerely,
Dr. Rachel Brennan, MD

A few final things worth knowing

• Melatonin-free, hormone-free, non-habit forming. Designed for nightly use without dependency or tolerance buildup.
• Third-party tested, manufactured in a cGMP-certified facility.
• Formulated for women 45+ navigating perimenopause, menopause, and postmenopause.
• 4.8 stars from 3,200+ verified reviews. 84% of customers in our most recent survey reported fewer 3am wake-ups within the first four weeks.
• 30-night guarantee. That is exactly the runway I would ask any patient to commit to before deciding if something is working.

Note: Sloom has sold out twice in the past eight weeks due to demand from this article. Stock is currently available — but if you are considering trying it, today is the right time. The new-customer discount cannot be guaranteed past this week.

P.S. Since this article has been shared widely, I have seen at least a dozen “menopause sleep” gummies appear online. Most of them, when I read the label, are simply melatonin in a pink jar with the word “menopause” added to the front. If you have read this far, you already understand why that is precisely the wrong tool for this problem. Please do not spend another month on it.
