School days (Monday and Wed.) and Sundays: usually by about 0100.
The rest of t he week: usually about 0400. Usually I'm up late IMing my buddies in Iraq and since they're 8 hours ahead of us, night is morning over there. I have a good group on my friends list though, and have people who pull different shifts, so usually I could have someone to IM 24/7.
Oh no matter what time I go to bed, I wake up by 0840 so I can get ready and be online by 0900. Me and my best friend usually talk at 0900. Of course class doesn't start till 1100. My schedule this smester RULES!!!!!
