Hi L.,
I took Ambien once, several years ago, for three nights, and had technicolor nightmares. Bad dreams are a side effect - and one that I just could not handle.
A co-worker also tried it and she had the whole sleeping but doing things you normally do when awake side effect. Literally, she would call me and/or her boyfriend, carry on conversations, and not remember any of it because she was physically still sleeping. Her BF finally taped one of the calls and played it to her to convince her that Ambien just wasn't the sleep aide for her.
Talk to you doctor about the dreams and any other side effects. Some people do really well with Ambien, but some just can't take it. 4
Me, I just take 50mg of Benadryl now when I need to sleep.
Good Luck
God Bless
