Mari, I had that problem for years. Medications sometimes helped, but mostly didn't. My pdoc is the no benzo, no sleep-aid kind of a man, so there was no encouragement from him to try anything specific.
Fortunately for me a muscle relaxant that I have been prescribed for lupus has helped. For the last couple of months that I've been on it, I've slept well.
Let me see - I know you must have tried a whole lot of stuff - maybe I could dig something up?
What kind of sleep-aids have you tried?
