Sharon,
I'm taking the regular Ambien not the controlled release. I am also taking Xanax. I suffer from panic attacks, I've been fighting with them fo 15 years, then was introduced to Xanax in 1999, a low dose 0.25 mg, I was never on any kind o psyhiatric medication until up to that point so now I am on Lamitcal, Vistaril, Ambien, and Xanax. Vistaril is a medication that hospitals give you after surgeries for relaxation i.e., shakiness.
I hope you find that the Ambien CR woks better than the regular Ambien.
Best of luck
-Andrea
