insomnia
"I'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'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's good and sad to know I'm not the only one."
