For school nights, I try to be in bed at or around 11 pm. I'll usually toss and turn for a few hours before sleeping, though...

I also usually take naps when I get home from school, which messes with my sleep schedule a lot. And when Summer rolls around, my sleep schedule tends to flip - I stay up later and later each night until I literally become nocturnal. About a month into Summer last year, I was waking up around 8 pm and going to bed around 9 am. Getting back on a "normal" schedule was grueling, and I'm not gonna let that happen this Summer!
