Now during summer I usually don't sleep until early morning hours, even when I've got nothing special to do - I just can't sleep and I spend time on the Internet. But during the rest of the year I usually drop dead on my bed by midnight^^
Lately I've been going to bed at 2-3am and waking up at 10-11. I'm trying to get my pattern back to 11pm-7am though
During school, 10:00 to 6:00. During summer, about 4 am to 3 pm. Random intervals of peeing and checking reddit throughout.
