Sometime between 10 and 11. I get up at 8 on workdays and try to make a point of getting up before 9 on weekends, otherwise my sleep schedule will get messed up.
I get made fun of for going to bed early, of all the stupid things. I guess there's something about needing a little more sleep than average and being responsible enough to get it that most people just find unacceptable.
Typically early morning no matter what I'm doing the next day. I might have nothing to do, I might need to be up at 6am, it doesn't make much difference. Even if I go to bed early, I tend to have trouble sleeping until it's around the time I'd usually go to bed.
