This is interesting to me - one, because I have a diagnosed major sleep disorder. (Both severe RLS and PLMD) I know I just never sleep. I don't eat that much, but I just darn keep gaining weight like a sitting hen. lol I've read before that people with sleep apnea often lose weight after being treated with CPAP machines - this ties in very neatly with that observation.

Now, if I could just get more than an hour or two sleep at a time...
