I generally get about 3-4 hours though it seams to be all i need. Though i dislike sleeping so little since only a month back i was on meds which were making me sleep 12 hours a night. I rely don't know what to do with all this extra time and for the record 3am is rely boring.
2 years ago i went through a period of 6 months where i was only sleeping a hour a night. that's part of the reason i went on those meds.
My sleep sucks too. At the moment I'm awake until around midnight, then again at some point in the night for a couple of hours (I lie there and doze on and off but I'm not asleep) and then I have another couple of hours before I'm awake anywhere between 6 and 7. Sigh. I hate not sleeping!
I bought these pills to help me sleep but when I take them, they make me tired for the whole of the next day as well.. So there's not really any point. But yeah, I wish I could sleep better. When I stay at a friend's place they're always asleep within like, 90 seconds of turning off the light and I'm just laying there for hours, hah.
Though i find the worse part is that i don't know when im going to get to sleep and generally stay awake until i crash, sometimes that can take two days. I dont mind sleeping so little but it would be good if my body was in a pattern where it would go to sleep and wake up at the same time each day.
I got 4 hours sleep this arvo and feel pretty good.
I cannot function without my sleep - well, I can function, but not in a socially acceptable way haha!
Apparently, to wake up refreshed and get proper rest and all that, you're supposed to sleep in factors of 1.5hours, ie., 1.5, 3, 4.5, 6, 7.5, 9 etc
So rather than 8 hours you're supposed to either do 7.5 or 9. It usually works for me, but most of the time I don't plan it properly.
I wish I didn't need to sleep so much, like Bop and Azmillan! Then I might actually get some study done...
Maybe we can help with some ideas!
