I think what frightens me most about DMSA and chelation in general is that there are very different opinions by even experts. For example, Huggins is against chlorella and algin, but others swear by both. I don't want to make myself worse, even though maybe I could make myself better, especially as a vegetarian who are supposedly at a disadvantage according to Huggins (agreed with by some same people who disregard Huggins on the sea-products, which adds to the confusion - either he is right 100% on detox or he is not). So, I am kind of "stuck" when it comes to the chelation thing, haven't decided yet what I am going to do beyond the diet and vitamin thing. In short, I am terrified of doing the wrong thing because my brain has been really affected by mercury already and I have ongoing mental symptoms.
