insomnia
"Really effective and helped me sleep, but also found myself confused and sometimes sleepwalking, in one case I was pretty badly injured jumping back into 'bed' but it was the home office desk I dove into, not the bed.  It was a strange experience, because I never walked in my sleep, and thought I could clearly see and knew where I was, it equaled "bedroom" at 2 am.  Take with caution."
