@Nammu that's frightening to think prescribed meds can do that! That reminds me that a good number of people sleep walk and become a different person. While in high school I used to jump out my bedroom window in the middle of the night and go places with no memories of it. The only reason I know is that sometimes I would wake up in different places. I remember the family used to talk to my dad while he was asleep. He would answer questions and talk like a different person. He had no memories of it after waking up. I've heard of other people doing the same.
