I'm sorry you are having such a time with the Ambien, I didn't take it as long as you but had strange side effects and stopped taking it. Lunesta worked but due to insurance I couldn't take that either, so my rhuemy prescribed Trazadone and I've been taking it for over a year now, and yes every night which there is nothing wrong with, some peope have insomnia for whatever reason and just can't sleep. I have missed doses of perhaps 3 nights worth and no jitters, or withdrawl symptoms like you described, but I did have a bit of difficulty staying asleep. Many years ago, my pcp gave me a script for klonopin and that was a nightmare and when you described your symptoms it reminded me of that, it was horrid! I had to just stop taking those crazy pills! I hope your rhuemy will figure out something that will work for you because sleep is so important! I have RA and when I don't sleep it makes for an awful flare.
