Holy $*&#, dude! I couldn't survive like that. I don't remember what I got in college, but it wasn't too horrible. I always set it up so that I didn't have any classes before 9am. I'd normally workout around 10pm to midnight my first couple of years, so maybe seven hours a night. That's around what I get nowadays, too.
I can't imagine being awake 22 hours a day.
I can't afford that much alcohol.
