Work.

Has anyone else fallen asleep sitting on the toilet at work? No? Ok, just me then. It's never actually happened (for more than a couple minutes), but if I close my eyes for a few seconds... I mean, I even try not to go to the bathroom for the first couple of hours because that's when I'm still sleepy...

ALSO, whoever said that extreme air conditioning makes for alert, awake employees has never sat in my office. There's a reason people fall asleep before they freeze to death.
