I don't take any sleep aids. Well, nothing prescribed by the doctor. Every once in a great while I'll take some OTC sleep aids. But those even leave me out of sorts that I hate taking them.

Your mentioning that you fell asleep going to to the bathroom reminds me of the times I've almost fell asleep while I'm running. I haven't yet. But I've been darn near close. I'll close my eyes and keep going. Somehow I stay awake. Glad you didn't hurt yourself! But dang that sucks.
