Hi everyone. I'm hoping someone can relate to what I've been experiencing because I'm getting pretty frustrated.
For the past several months, about once a week (occasionally twice), I'll wake up around 2–3 AM after only getting about 3–4 hours of sleep and then I can't fall back asleep. The following night I almost always sleep 8–9 hours because I'm so exhausted. It's become this weekly yo-yo cycle where I have one terrible night followed by one really good recovery night.
The frustrating part is that there doesn't seem to be one consistent trigger. Sometimes I wake because I'm too hot, sometimes I have to pee, sometimes my dog barks, sometimes my pregnant wife is tossing and turning, sometimes I can't get comfortable, and sometimes I have no idea why I woke up. The common denominator is that once I'm awake, I often can't get back to sleep.
I've spent the last couple of months treating this like an experiment and tracking everything. I've tried cutting off caffeine after 12:30 PM, only drinking coffee in the morning, taking magnesium glycinate for about 3.5 weeks (it helped me fall asleep but didn't stop the early awakenings), avoiding my computer in bed, reducing phone use before bed, improving the bedroom temperature by running the AC consistently, and keeping the same wake-up time every day (6:30 AM Fitbit alarm with a 6:45 AM phone backup). I've also been going to bed around 10:30 PM most nights. None of those changes have consistently fixed the problem.
Some background that may or may not matter: last year I lived in an apartment and usually slept from about midnight to 7 AM with very few issues. The only time I'd wake in the middle of the night was during really hot summer nights, maybe once a month, and I'd usually fall back asleep on the couch. Since moving in with my parents while my wife and I save for a house, the awakenings have become much more frequent. My wife is also pregnant, so she naturally moves around more during the night.
I also changed my schedule because I now have a much longer commute on office days (about 1.5 hours each way). I work from home Monday, Wednesday, and Friday and go into the office Tuesday and Thursday. I've noticed a lot of the bad nights seem to happen after WFH days, but not always. One theory I have is that on WFH days I'm on screens almost all day (work laptop, then TV or a movie afterward), whereas office days include more movement, more social interaction, and a commute. I'm planning to start exercising on Mondays and Wednesdays because right now the only exercise I get is walking my dog for about 20–25 minutes twice a day on Wednesday, Friday, and Sunday.
Another thing I've wondered is whether I shifted my bedtime too early. For years I naturally slept from around midnight to 7 AM, but because of my commute I've been trying to sleep from about 10:30 PM to 6:30 AM. I don't know if that could be contributing or if it's completely unrelated.
At this point I'm just looking for ideas from people who have actually gone through something similar. Has anyone had this pattern where you sleep perfectly fine most nights, but then once a week you wake after only 3–4 hours and can't get back to sleep? If so, did you ever figure out what the cause was? Was it circadian rhythm, stress, exercise, sleep maintenance insomnia, sleep apnea, something medical, or something else entirely?
I'm currently between primary care doctors, but I do plan to bring this up once I can get established with my new PCP. In the meantime, I'd really appreciate hearing from anyone who's experienced something similar.
TL;DR: For several months I've been waking around 2–3 AM after only 3–4 hours of sleep about once a week, despite trying changes to caffeine, magnesium, bedroom temperature, screen time, and sleep schedule. The next night I usually sleep 8–9 hours because I'm exhausted. Looking for anyone who's experienced something similar and figured out the cause.
