What do you do when you cannot sleep?

Everyone has insomnia here and then. What do you do to pass the time (supposing that you've tried everything to fall asleep and couldn't)?

I usually read (that's how I finished most of the books of the Royal Assassin series), or sometimes, when I feel inspired, write. I spend my night on the computer quite rarely, cause we live in a 1 room flat, so it can bother his sleep.

REad, go online mostly. Play videogames on some portable console *shrugs*

Reading is good, that's how I finished most of the books that didn't captivate me until then

Bwehehehe

I never had insomnia. Most of the times it is just that I DON'T want to sleep just yet

you're one lucky woman. most of the times when I cannot sleep is either when he falls asleep before I get in bed, or if it's too hot in the room, which is pure torture.
the last time I had insomnia I used the occasion to do my nails. all 20 of them

I write on a random story of mine (usually Ductape lately) or I draw emo-fanart (mainly of Creed lately). :)
