Well, I hate to answer for Vaude, [http://www.escapistmagazine.com/profiles/view/VaudevillianVeteran] but since she doesn't come here to Off-Topic, I'll say for her that she doesn't sleep, except every 72 hours or so, when she slips in and out of conciousness for about 6 hours, and occasionally has an hour nap, then carries on as usual.
(Or that's what she says)
Me, I sleep irregularly, starting to try to get to sleep anywhere from midnight to 9 in the evening the next day, mostly around 4-5 AM.
I usually start trying to get to sleep at 2 or 3 though. I then get up at 6 or 6:30.
I sleep mostly on my side, facing the door, slightly curled up.
Usually I wake up by sitting bolt upright and throwing the nearest object at my alarm on the other side of the room, so I don't know what position I move to, but I'm usually right on the edge, and occasionally hit my head on my bedside table.
