I've had fibromyalgia for 5 years now and the insomnia part is out of control. Saw a new sleep doc, and I don't know how I can do what he wants me to do! I did a sleep study - I had, as they put it, extremely light apnea only when I had nightmares. But since my doc wants to try me on xyrem, he said I have to use a bipap - and just found out yesterday that he needs what he calls "full compliance" - which in his words is having it on 7 hours straight, every night, no matter what.
