By the way, few years ago, I started chelation therapy, after reading the story of Matteo Dall'Osso, a young boy with MS. He wrote in his blog, an amazing story (his true real life) which describes his struggle against MS and a sort of narrow-mindedness of some neurologists. This is the link of his blog (completely for free) to read or download his story.
Currently he feels much better, and had many improvements, thanks to some supplements such as: Glutathione, B12 Vitamin and other... in addition to chelation therapy.

I tried the same route, but I didn't reach great improvements. (I think).
