I took Cyclobenzaprine 20mg from 2006-2009, along with Oxycodone, Nortriptyline, Sulindac before I was diagnosed with FMS. But didn't seem to help any at least with the back pain, I didn't know at that time the difference between FMS (joint stiffness/pain) and my back pain.
I just (2/2011) found my Vitamin D tested at 13 which is very low so started 5,000 iu a day. Had xrays done for chiropractor and my spine is twisted, which is probably the source of the FMS as it's been that way since 1983 and has been a constant pain. We increased the Concerta to 27mg to provide more focus, but very happy with the results so far as it's greatly decreased my ADHD symptoms. Still struggling with insomnia.
