Yeesh.
It's hopeless; I can't seem to get to bed before 3 am. Last night, I was playing chess with some Russian dude (clobbering him quiet easily, because well...I'm good at chess :P) until almost 6 am.
Never mind going to bed "when the sun was coming up". By 6 am in London, the sun's already been awake for two hours.
Very weird, very cool.
