I'm jealous. If nothing wakes me up I can easily sleep 24 or more. Usually after 16 or so, I start getting those dreams where I try to wake up but am trapped in the dream.I'm fine with 7, that's about my average, can function perfectly well on 6 and never get more than 8 hours. Even if I have no reason to get up and nothing disturbs me I just can't sleep more than 8.
In my teens and 20's I used to be able to sleep 12 hours easily and could barely crawl out of bed on less than 7.
I've been like this since I was a kid. I've got really bad restless leg syndrome, and the meds help, but I still don't get very good sleep. If I don't get a long sleep on the weekend, I start to get the standard sleep deprivation symptoms. Cranky, can't concentrate, I'm basically a mess. This usually means I only get one decent day on a given weekend.Are you depressed or sick? That sounds pretty unusual.
But I was just thinking about this today. I've been trying to get myself on a steady sleep schedule, but I'm not positive how many hours is ideal. I used to sleep an even 8 hours every night. Maybe up to 9 if I was really tired from missing sleep the night before. But that's been very gradually decreasing as I get older. I think it's now around 7:20, possibly now as little as 7 hours.
Too much and I'm up an extra couple of hours and my sleep schedule is wrecked. Too little and I crash and burn late in the early evening and it's everything I can do keep from napping. To somehow stick to a schedule I've been forcing myself off the computer at least an hour before I plan on turning the light out, and reading for most of that time.
