Insomnia
"I took Ambien CR for a year and at first it worked pretty good except for a minor side effect that left a bad taste in my mouth. I didn&#039;t let that bother me as long as I was getting my 8 hours sleep. After a year it stopped working so I tried to double my dose. Big mistake, I had to stop using it because I started sleep walking and having conversation with others without remembering anything. Ambien works but be cautious of side effects."
