I am using just DMSA right now, 50mg every 2 hours. I started off with 25mg every 4 hours and worked my way up to where I could 'feel' the chelation happening via muscle stiffness, especially in my neck.
Candex did work for me really well before--however, if I stopped the Candex, the candida symptoms would come back in a day or two. Now though, ever since getting my fillings replaced, the candida doesn't come back as it did. Any symptoms that do return take much, much longer than they did. Also, I have pretty much stopped the candida diet completely without much problems.
