I've had an Ambien prescription for some time - always have had sleep problems, even before dx. Works pretty well for me, but generally I only get about 6 hours sleep with it. Then I'm wide awake. Every body is different, of course, so it's hard to say how it would work for you.
I'm not sure about taking it long term though, so I try to go without it when I can. You can become dependant on it, even though it's not in the traditional sense of a narcotic medication. I'm thinking of asking rheumy for something else. My Ambien script has actually been coming from my PCP.
