In an ideal world, I would go to bed at 11 to wake up at 7 for school or work the next day. I would get 8 hours of sleep and get all my homework done right after school. On the weekends I'd have everything easy and sleep in after going to bed maybe midnight...and at FIRST events there'd be no stress and no partying so I'd also get a good 8 hrs of sleep.
Hah! This is not an ideal world, you fiends! Sleep is for the WEAK!
So, consequently, I doze off anywhere from midnight to 3 AM or 4 AM on school nights (depending on homework).
Some weekends I go to bed 11 or 12, other weekends I have fun things to do and watch movies late into the evening and end up sleeping at 4 or 5 am, if not after sunrise.

Yay for no sleep. Don't even get me started on FIRST events.
