Hi Minnie,
I have these problems and I don't even have fibro!

My wife has fibro (I have other chronic pain issues) and has found some relief/ways of coping with
mindfulness meditation; she meditates for 20-30 minutes twice a day. She's pretty good when she can do her thing, and pretty bad when she can't/doesn't work it in.
I can't/won't make any promises (it doesn't work for me, for example) but
if it can't hurt to try it, then it can't hurt to try it.
Another technique I've tried (with limited success) is biofeedback.
Have you been able to identify any triggers? Eliminating food triggers and making other lifestyle adjustments have been more effective than we thought.
What is it that your doctor prescribed that your insurance won't cover?
Doc
EDIT: This just in...
