Sunshine, I don't doubt that you were ill, however imo you were probably ill primarily from parasites or from nutritional deficiencies, and not mercury. I find it very hard to believe that chelating with a dosage of 5 mg of ALA has made such a big difference. I am chelating with 200 mg ALA and 100 mg DMSA every 3 hours for 3 day rounds. I have done over 50 rounds of chelation, although many were with ALA in the range of 50-100 mg a dose. I think I will probably try to chelate with 200 mg ALA +100 mg DMSA for another 3 or 4 months, until I use up my DMSA supply. If I don't show major improvement by then, I think I may give up on this and look for some other treatment.
