Ambien CR and blackout

after taking ambien CR for a few months with no real side effects all of a sudden I started doing bizarre things with very little memory of doing them, I walked around the house in the middle of the night in a blackout I cleaned things, ate things, made phone calls to friends and they couldn't understand me because I was slurring my words, My family said I was acting very drunk swaying back and forth and not making any sense. I"ve driven places and don't remember driving and that is enough to make you say o.k. something is wrong with this medication

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!!
