apart from "go to sleep now", obviously. I'm gonna do that in a bit.

I have to get in WELL early (like, 5am) for work tomorrow because I'm naughty and not done all the work I need to do before my boss gets in, and I'll be wading through LARGE AMOUNTS OF SHIT if I don't.

I don't trust myself to wake up early, ever, so how the hell should I make sure I don't oversleep like the sloth that I am?
