ambien is some bad stuff. that was the third sleep med my dr tried me on trileptal and lunesta didn't work, either the ambien didnt' put me to sleep ( I stayed up 8 extra hours reading a book once) or once my husband came home one night from a trip after I went to bed and I didn't know he was there and apparently we had fun and I didn't remember it at all, I thought he was lying to me. Of course he used to do electrical work on the house on it! I had to make him stop using it I was afraid he was going to get electrocuted.
