Just a suggestion for those suffering from fibro/cfs. Have your blood calcium levels checked. If they are above normal it could be a sign of parathyroid disease which causes high blood calcium....and symptoms almost identical to fibromyalgia....which I suffered with for many many years.
I had a mini surgery to remove the bad gland and ALL my symptoms are gone as is ALL my pain.

this is probably most certainly not the magic bullet for everyone, but it is sure worth looking into......I did and it changed my life. There are a few good sites about parathyroid disease and symptoms on the web. The one that helped me the most was Dr. Jim Norman's of Tampa. Check him out and be sure to look at the symptoms.

Good luck .
