Ambien CR and acts

I have been taking ambien cr for over 2 years. I did not realize I was having side effects until I started to notice things, and my family would tell me things. I was cooking late at night, full meals and eating them. This I would do either for my self or me and my son. He said I would carry on conversations with him and clean after I was done. I have gotten in my car and went to visit people, or went to the store (no memory of these acts). Just this morning I woke with a band-aid on my finger. Called my husband at work. He said I was washing dishes and he had been watching me do this.He said I cut my finger with a knife on accident and I said "ooh, i cut my self", and then I said "oooh look, there's blood". He immediately took care of it but he noticed I could not stop stumbling and I just stared at my finger like a zombie. Evidently I continued this behavior for over an hour and a half. He assumed I was awake because I was talking to him. But my words were limited and only in phrases. He took me to bed and I went straight to sleep. Just a few days ago, my husband was telling me about me and my son going to the store one night. (no memory of this) Now he is scared and he hides the keys, although he is a heavy sleeper. First he thought this was kind of funny, because I seemed so lucid. Now he has taken note of things. Like damages to our car, my new found OCD (with no memory of fixing and cleaning things), my need to be left alone and expressing this only at night, and how I don't need him in my life and how I feel I am a horrible person, all of these things occurring at night after I have taken my ambien. My biggest concern is the sleep activities and knowing that I am involving my son without knowledge. Thank goodness he has not been injured. How would I know if I have hurt someone with my driving? I don't. If my husband hides the keys and he wakes up and the keys are on the table and the vehicle is parked different. He knows it had to be me. I have even gotten dressed and went to the club (no memory of this, people telling me about me being there cause they saw me). And me seeing the clothes I wore laid out on the floor. Yeah, its gotten out of hand, I want to stop taking it, I need to. I tried and stayed awake for 8 days and then slept for 3 hours.Depression is only there when I am on the ambien, not when I am awake during the day. I have lost track of times and events. Memory loss is a horrible thing. I can't remember things from last week or last year. Its like gaps in my mind. Scary, yes, heartbreaking definitely. The breast pains, I thought that was just something new going on with me, still may be. I have to wear sports bras, to constrict any movement, if I don't it feels like someone hit me in the chest with a bat. I tried Lunesta (the rashes were unbearable). As you can tell, I am an insomniac. I am not sure what to do. I will call my doctor but I thought the sleep activities were not real. Now I know they are.
