"i&#039;ve been using ambien for about 4 to 5 years now. i also take a pain medication for a back injury. my doctor switched me to ambien cr and the side effects were horrible. i felt angry beyond my control, confused, experienced memory loss, and crazy hallucinations. this was about 2 weeks ago and i&#039;m still trying to put the pieces together. make sure if you take this pill you check for drug interactions and be in bed ready to sleep. it&#039;s good and sad to know i&#039;m not the only one."
