I have not slept well for many years. I tend to fall asleep with no difficulty (usually between midnight and 1:30), but then I'm awake again in a few hours--these days in four or five hours, very occasionally six. When I'm sleeping particularly badly, it will be in two or three hours. My indexing work requires concentration, and I seem to be able to work well despite the constant bad sleep. I've tried various things over the years--melatonin, CBD gummies, limiting coffee, even gave up drinking for three months. None of these produced much effect. The CPAP machine was a total disaster. WTF, I'm in relatively good health and function at the age of 72, so I guess this is just the way it is.

I tend to stay up too late for my own good, but I don't normally have to set an alarm, so I was getting as much sleep as I needed, and felt great! Lately, the new "pool guy" has been coming super early in the morning and making a bunch of noise outside my window, so I get woken up before I would normally wake up. Guess I'm going to have to try to train myself to go to sleep earlier until this guy starts observing our "quiet hours." Sometimes I can get an extra hour or two of sleep after getting woken up.

I do not function well without enough sleep. I have a hard time on days I have to wake up super early for work, sometimes only getting 3-4 hours of sleep. Not safe for me to be driving home when I feel like nodding off. Can't concentrate so I don't get much done. I'm glad I mostly work in the early evenings. That's the time I can shine, if I've got a good night's sleep the night before!

It depends on how I feel. I have taken to napping during the summer when it is too hot to do anything outside, then being up half the night, when I feel sleepy, I go to bed, then I get up when I wake up.

I sleep more than I probably should, but I'm retired, so I can get away with it. I think that I was probably a cat in a previous life, lol. They seem to sleep most of the time.

Average of 3-4 hrs a day , working nights .
Average 20 hr of sleep per 5 days . Then , when finally off , I can sleep like dead for 14 hrs straight .
I don’t know about health impact . But memory impact for sure . By day # 5, I can’t remember my zip code at gas pump
Or simple things , like what day it is .
Also I can sleep like a horse standing up , and I have slept for seconds while driving or infront of my computer at work
