I go to bed WAY early by your guys standards on the weekdays...
I'm usually asleep by 1230 on Sunday and tuesday nights. On Thursdays, I usually pass out about that time. It's that Early because I have Organic Chemistry at 9:30, and the one time I didn't shower I fell asleep in that class, and ended up missing a question on the test

so now I'm superstitious.
The past month or so, I've been going to be earlier on Thursdays, or not passing out...I have to be up and to our union by 745 for my role as a Student Ambassador for the College of Arts and Sciences at campus visit days.
On the weekends, depending on how much I drink, I'll usually stay up until 230. I won't get up til noon, unless it's an early football gameday.
