I wake up at 4am, or close to-- since the time change, it was 3, and then gained 5-10 minutes every day until I was back to 4am.
I don’t know why.
I am an inveterate insomniac, and take several medications to deal with it, including 2 PRNs for times when I travel, my schedule is otherwise disrupted, or unusual stress is keeping me up.
I was going along on a combo of meds I’d been on for years, and waking up around midnight, falling back asleep between 12:30 & 1am, waking back up at 2:30 unable to go back to sleep, so taking a small dose of something-- what I took depended on how much longer I could sleep.
Then, my doctor added one more medication, and now I fall asleep almost immediately after I go to bed, and as long as I go to bed after 7pm, sleep until 4am, almost on the dot.
I shoot for going to bed at 8:30. 8 would probably be better, but just isn’t realistic; some nights it’s 9, and I feel fine the next day, but a few nights of 9pm-4am in a row, and I start to feel tired all the time.
I usually take a nap on Saturday afternoon for about an hour, but not on Sunday. I never sleep otherwise during the day unless I am sick-- in fact, the first sign I am sick is quite often napping on a weekday, falling asleep after dinner, or sleeping past 4am. In fact, on days I have to work, I set an alarm, even though it isn’t necessary-- except that 1 time in 1,000 that I’m coming down with something.
