You also might want to look into "low dose naltrexone." It seems that many MS people have done remarkably well with this. (Look for an MS blog that is discussing that topic for further input.) I take it at bedtime for fibromyalgia and I no longer have any of the symptoms affiliated with it.
I'll explain how it works, although I am not a health professional so I may get this wrong.
I believe what happens is that the low dose naltrexone temporarily blocks your opioid receptors. So your body thinks that something is trying to block its endorphins and it begins to produce more than you were producing before. Somehow this helps not only people with autoimmune diseases but also cancer and many other maladies.
My girlfriend takes it for Ankylosing Spondylitis. She also has gone with a no-gluten diet and has control of her symptoms too. She also has restless leg syndrome. I have no idea what that is, but this helps with that also. Could that be what you have? Wikipedia has a lot of info on this.
I believe that the patent has long gone away so there is not profit in producing this for the drug companies. So the only way you will probably hear about it is through word of mouth or blogs. Just make sure you get a really good compounding pharmacy to put it together because certain fillers like calcium carbonate will not allow it to work properly. I found my pharmacist on the website dedicated towards this subject. He is in Florida. Best of luck!
