I took ambien CR for about 5 months every night. The lower dose didn't have much effect but I was sleeping well with the 12.5 dose. I did not have any of the bizarre sleep behaviors that many have described. I did however realize that it was producing severe anxiety. I stress this is not my normal level of life anxiety. I began to realize that I was in a constant state of "edginess" and it was getting worse and worse. If could not relax at all and felt like I was going to jump out of my skin. Within a day of stopping it the anxiety was gone but of course I had severe "rebound insomnia" going whole nights with 30-90 minutes of sleep. Tried lower doses but with daily use the anxiety came back. Trying lunesta now and hoping for normal sleep some day
