Depends on the day. I 'usually' get 5-6 hours of sleep on the weekdays, and 7-8 on weekends, but it varies. Sometimes I get as little as 4 hours of sleep (and can't function all day after that), and sometimes, I'll sleep as long as 9-10 hours when I'm exhausted. I really need to fix my sleeping habits though. Not a good thing to sleep so late. I don't feel good when I get less than 6 hours of sleep...and sometimes, even that is too little.
