I was put on Ambien CR to help me fall asleep and stay asleep. It worked great! It did everything it was supposed to, and then some. And by that, I mean it caused rediculous side effects. It caused confusion and basically made me feel as though I was high. I got up to use the restroom once, and I fell into the door! I also learned from my ex-boyfriend that I would call him and say things that I ordinarily would never say! I am a conservative person, but I guess on the phone, I was not so conservative! And the bad part was, I did not even remember saying those things! Other people I talked to who had taken Ambien also had experienced the same problems. I also noticed that I still felt strange the next day. So overall, Ambien CR does put you to sleep and help you stay asleep, but I'm not sure if the side effects are worth it. Personally, I have had the best luck with Tylenol PM!
