Empty containers symptoms and conditions

Developed sleep walking, eating, talking, running machinery and watching TV while I was supposedly asleep. This was witnessed by my niece who was very scared. It lasted for about an hour. This is not the first time but this is the first time someone witnessed it. I had suspected all along because I saw used dishes and empty containers in the kitchen in the morning. Have been off it for 3 days now and thank God. Never will I take it again although it seemed to work well for 2 years. I have gained so much weight from the night eating. That guy on the news who says he drove his car after taking Ambien, I now believe him!
