I can usually always sleep. it just happens, for me. not always a good thing.
true story: I fell asleep playing my viola, once.
I usually pull all-nighters with the vidya games, if it's already late. I heard somewhere that just plowing through it is better than sleeping for 2/3 hours, or something like that. anyone wanna validate that?
I draw pictures of anime or real animals then when i feel tired enough to sleep, I go straight to bed and i fall asleep right away.
mostly works for me and that way i don't wake up anyone at night time xD
