well lets see.. I work from 430pm to 1:30 am.. get home about 2am, have to check my email, annadtech, etc. can't get "wound down" for sleep until about 3, sometimes 4am. fall asleep about 4, 4:30. I get up for school at 7 every weekday, (college freshman), go to school from 8 to 3ish. then its back to work again.
so I average 2 1/2 to 3 hours weeknights. weekends are a different story. I'll go to bed at the usual 4-4:30ish, and not wake up until 3 or 3:30 pm the next day.

lets me catch up on my sleep
