My husband suffers post traumatic syndrome. He was prescribed Citalophram. He cut his medication in half and in just a couple of months he attempted suicide. His medication was increased as well as Lorazepam. He takes Ambien CR to sleep. About 2 months ago, while in REM he stated acting his nightmares. He has pulled my hair, punched the back of my head, and kicked my leg. He has thrown the bedside lamp and punch the mattress. He abruptly wakes up after acting out, remembers what he had done but vaguely remembers his nightmare. I feel I am in danger. Could this possibly be happening because of his medication? Is this a sleeping disorder? What can I do to help him? Thanks!
