Hi Teri.

Perhaps you should try alpha lipoic acid, according to the Cutler protocol. You can do it with or without DMSA, I did it without DMSA, because I don't believe I need it. This is the standard anyway, most use it, and the results have been good.
It has worked very well for me, and my main problem has been candida. I solved my constipation etc. with anti-candida diet, I think I had the diet just 2-3 months, the first few weeks gave die-off and terrible constipation, but after that things just started getting better. Now I'm cheating like a crazy with the diet, and I get away with it.

I haven't heard anything good about other chelation protocols, and the products you suggest, they tend to be more harmful than useful.
