I have been using Ambien for about 2 years now for sleep. I still wake up during the night, but can get back to sleep easier. I know the manufacturer says only use short term; I'm not sure if that warning is there because of possible dependency or problems with sleep cycle. Personnaly, I don't care if I've become dependent on it, I'm dependent on my Verapamil for my heart arrythmias also so what is the difference? But I do wonder if my sleep is less restful as a result of the long term use of the Ambien. I've been recently started on Klonopin because of severe twitching in my sleep. If I take more than a .25 (1/2) tab I'm too drugged up the next day. Between the Verapamil and the Klonopin, I sure get some wild dreams--that sure dosent help the sleep problem either. Anyway, I wonder if anyone else has used the Ambien for a long time and how it has affected you. I do plan on trying the ZMA that the moderators suggest.
