I have been taking Ambien CR for a few months. At first it worked o.k. but now I am having bad side effects to it. I am walking around the house in a stupor, trying to talk to my family, slurring my words, acting like a drunk,cleaning the house, eating and not remembering any of it until my family tells me about it. They even think I am taking some sort of mind altering drugs because of my bizarre behavior. I don't like talking to someone and not remembering it. I am stopping this medication immediately before I do something to hurt someone while in a blackout!!
