I found myself pretty wired last night... couldn't sleep at all, not 'til 2 or so. Should make dim sum interesting this morning. Interesting thing, though; I decided not to post on LJ about it until morning, and went back to bed... and it didn't help, not really.
Well, there goes the theory of all the people who sit around, posting "Here I am, I've got insomnia, and what do I do? Post about it to LJ. I'm sure that's why I'm not falling asleep." No, actually, it's not. I've got your counterexample right here. Post away.
