Looks like no one has responded to your query yet. Here's an idea from me. I had extreme mercury contamination and took two actions which helped enormously.
1) from my physician I had IV administered chelation therapy, 3 rounds of 10 injections/
2)I continued chelation with a product sold in the US as HMD (for heavy metal detox).. One of its unique ingredients as I understand it is an herbal extract that facilitates complete excretion of the metals that the solution mobilized. If you mobilize metals faster or in greater quantities than your body can excrete, then you will simply re-process those metals that have entered your bloodstream but have not been excreted, making you sick.
