Not everything you read on the internet is true, or, at least, in relation to you. Trust me, it does more harm than good looking up stuff like that on the internet.

Like the other poster said, try bringing it up with your roommate. I tend to pace a lot before going to bed, so I'll probably try to wean myself off of doing that, but, in the mean time, I might tell my future roommate that.

Have you ever brought this up with a doctor? Your sleep talking problems and whatnot?
