Sleep fall.

I must of passed out sitting at my dining table. I know this, as I just woke up falling from a chair, which ended up on its side, 1/2 a second before I hit the floor. I don't think I broke anything, though I can feel a nicely bruised side developing, like a badly taken Polaroid. It's not the first time I've woken up where I shouldn't be, the worst was hovering at the top of my stairs, just about to fall down them. Adventure sleeping. Bugger.
