Hum, I'll take your word on not thinking too much as it may make it harder to get back to sleep. I had switched in the last few weeks to turning the light on and standing up, rather than sitting down in the dark. I've also started taking a low dose (3 mg or so) melatonin on my first wake-up trip.
I'll say I never get up more than 4 times, usually twice, I think. Pretty sure as I am awake for some time before I get up, keep trying to just go back to sleep and when it doesn't work I figure might as well go pee. I am dealing with other emotional issues, including aging. These all combine to keep me awake. But, as I generally stay awake during the day I must be getting almost enough sleep. I remember lots of dreams, i.e., REM sleep.
I feel extra high levels of fatigue lately, but I am taking a new depression medication which may be causing more problems than it fixes.
I purchased a Fitbit One as I found a page here which specifies which trackers are used for sleep and which aren't. Also, the Fitbit One seems to be a popular model as per the number and positivity of reviews on Amazon. I hope it works.
Hope not smoking cigarettes - but that's another subject.
I don't have any help on the tracker question, but when I get up to urinate I am awake enough to write the time down.. I don't but usually look at the clock to see how long I have been asleep. If it is three or four hours I don't think much of it, shorter I wonder why.
I am a senior so night time needs are normal for me. There is no fix.
