Is it bad to sleep face up on Xanax? I'm currently in bed beside my boyfriend who is bared out on Xanax. I can't sleep because I'm afraid something will happen to him and I won't be awake to help him. His breathing is heavy. He is sleeping face up because I got someone to move him for me because he was taking up half the bed. I need room of my own since I'm pregnant I can't just go sleep on the couch. Please someone reply. I don't know if I should try to move him on his side.
