My friend has a sleeping disorder, and he takes Ambien. The problem is, he sometimes hallucinates off them. He's tried other stuff but nothing works, and some leave a bad taste in his mouth the entire next day. He also has dreams where he wakes up and is half awake but still dreaming, and the other night he said something was crawling all over him. He said he has spoken to 3 different doctors about it. Does anyone else suffer from problems like this? What do you do about it?
