I thought perimenopause and middle age were making me exhausted. After years of searching for answers, I learned I had severe sleep apnea.

"You have severe sleep apnea," the doctor told me in his office while peering into his computer screen at my data. I definitely wasn't expecting to hear that.

At 48, I'd spent years assuming my exhaustion was simply a symptom of my stage of life. I was a working mom raising two school-aged children while juggling a busy freelance career in a chaotic industry. Like many women in midlife, I also suspected perimenopause was playing a major role. Being tired all the time felt frustrating — even devastating — but not particularly unusual.

The problem was that my fatigue seemed disproportionate to my life.

I was exhausted constantly, even with eight hours of sleep

For at least five years, and probably longer, I felt exhausted almost constantly. I wasn't just a little sluggish. I felt like I could soak up sleep like a sponge. Whenever I sat down, I felt (wished, really) I could drift right off.

What confused me most was that I wasn't actually sleep deprived, despite what people assumed. Most nights, I get a full eight hours of sleep, even during weekdays. Yet after getting my kids out the door for school in the morning, I'd often climb right back into bed for an hour or even two. At some point, I stopped calling it a nap and started thinking of it as simply finishing my night's sleep; the rebranding made me feel a little less ashamed of it.

I used to be someone who woke up before dawn for a 6 a.m. spin class, or glommed onto other hiking groups at a trailhead for safety when I started a solo day hike in the dark because I was awake without an alarm. I had energy. I felt vibrant. Over time, though, I began organizing my days around opportunities to rest.

I hated having to do it. I was ashamed of my excessive need for sleep.

I spent years searching for the reason, and for a solution

Because I assumed hormones were the culprit, I spent years trying to solve the problem from that angle. I tried various hormone treatments, including patches, creams, and even testosterone pellets. I experimented with prescription medications intended to boost energy and alertness. Of course, there was plenty of coffee involved, too.

Nothing made a noticeable difference.

Meanwhile, fatigue was my standard answer whenever any doctor asked if I had any concerns.

At annual physicals and routine appointments, I repeatedly complained about being tired. But years went by without any measurable progress.

My general practitioner suggested a sleep study

Recently, my general practitioner suggested I get a sleep study to "rule out" any sleep dysfunction as the culprit.

I was skeptical.

I didn't think my problem had anything to do with sleep. If anything, I thought I was getting too much of it. Sleep apnea wasn't on my radar. I associated it with people who snored loudly, which I don't, and I know that it's linked to obesity. I'm at a healthy weight for my height, and my weight has stayed more or less the same for the last decade.

But I liked the idea of ruling it out: If sleep apnea wasn't the cause, at least I could cross it off the list, and all future doctors would know I'd already turned over that particular stone.

So I agreed to the sleep study — and the home test confirmed that I had severe sleep apnea.

I was truly stunned at the diagnosis in the specialist's office. Suddenly, years of unexplained exhaustion looked different. Maybe the issue wasn't that I needed more discipline, more caffeine, different hormones, another supplement, or just to push through. Maybe there was an actual medical reason I never felt rested, no matter how much I slept.

I'm still adjusting to life with a CPAP

I won't pretend I was thrilled when I learned that sleeping with a CPAP machine was my next step. It's definitely "not sexy," I said, when my sleep doctor asked me what I knew about CPAPs. But he offered a perspective that validated and stuck with me: There's nothing sexy about being exhausted all the time, either.

For the first time in years, I have something I didn't have before, something I could really work with and seek a path forward: an answer backed by hard data.

Now, after about a month of treatment, I'm still adjusting to life with my CPAP machine. Between travel and an inconsistent seasonal schedule, I haven't established the perfect routine yet, and I can't honestly say I've had a dramatic, overnight transformation. But the usage itself has been easier than I expected, and I'm cautiously optimistic that the benefits will become more noticeable with time.

Even now, it's reassuring to know I'm treating more than just my fatigue. Severe sleep apnea is associated with increased cardiovascular risks (among other risks) if left untreated, so even if I don't yet feel radically different day to day, I like knowing I'm doing something important for my long-term health behind the scenes.

Because I'm still adjusting, I don't yet know exactly how much of my fatigue can be attributed to sleep apnea, or how much perimenopause and midlife changes — or other factors I don't even know about — may still be contributing. What I do know is that after years of chasing explanations and trying remedies that never fully worked, I've finally identified a major piece of the puzzle.

And for the first time in a very long time, that feels energizing.
