I sleep *wayyy* too much. Most of the time I don't mean to sleep 12 hours, it just kinda happens. I joke that I'm still catching up on sleep that I didn't get a year ago; during that time I only got 3-5 hours a night. I worked from 5am- 11am, then school from noon-4, then work again from 7PM- 2AM. That was a hellish year. I was also taking 20 units in school - but some how I managed the best GPA of my scholastic career.
An average night, I sleep around 9-10 hours. The most I have ever slept was when I slept through the fourth of July- a complete 24 hours. I wasn't under the influence of anything, just really exhausted from working 6 days straight, pulling double shifts. I also didn't intend to sleep through the 4th of July, it was supposed to be my day off, and my apartment had around 20 people staying there for that party- how the heck could I sleep through all that noise I will never know. I was told that it was one hell of a party.
