LL, by all means go ahead. My intention was not to confuse anyone here, just DMSA doesn't look very good on paper to me. If it helps you, then it should help a substantial amount of the population in countries where amalgam fillings are used, because everyone is mercury poisoned to some degree. DMSA was originally developed to treat perhaps a larger scale poisoning, the exposure from a few fillings over a few years seems a bit small for that (this was your case). Perhaps some of its efficiency comes from chelation of lead too, or methylmercury? Or some other undocumented effect. Who knows. Some sources even claim that DMSA chelates brain mercury, which doesn't seem to be true.
