Really? I'm lucky to get 5 hours of sleep a night. I've done all nighters. I usually get 3 or 4 hours on school nights and I'm totally alert at school some days and sleepy on others. Might do an all nighter tonight again with all of the homework I need to finish.
No hours, or 10 min I actually end up buzzing (feeling wide awake) and then crashing at about 7pm. When I started at uni (and was determined to both go out and get to my 9am's) I would have had about 3hrs for between 2-3 nights a week. What can I say. I work hard, I party hard, I sacrifice sleep.
