Now the question is, what time do you usually wake up on weekends?
When it's Friday and I play until midnight, I usually wake up at 7:00-8:00, know the first thing I do? Get on the computer. When I'm not playing until midnight I usually wake up at 6:00-7:00 in the morning.
Uhhh...on weekends? Honestly, it depends. Usually, I'll wake up somewhere around 8 or 9 am after going to bed at somewhere around 12 pm. However, if I stay up late(like 4-5 am late), I'll usually not go to sleep at all, then doze away on and off throughout the rest of the day. Like a cat, kind of.
My sleeping pattern tends to go out the window on weekends - I wake up anywhere from 4am to 2pm, and occasionally even out side of that sleeping range. It really is a case of getting back into a rhythm in the rest of the week, then having a great time mucking it the hell up.
I get up around 6:00-ish AM because I want to get my weekend rolling But I stay up till around 2:00 AM so its probably not healthy to have four hours of sleep, maybe that's why I crash-and-burn on Mondays
