I feel like giving up. I cannot seem to tolerate chelation at all. Down to 6mg of DMSA headaches and dizzines within a few hours. Feeling not too bad physically but emotionally wobbly as i wouldnt bother at all not with chelation. Every time i try to chelate it begins to feel too much. I recently tried HMD (heavy metal detox) which is hailed as a very gentle chelator with very few reported side effects. Well it made me ill. I should have known better its got chlorella in it.
