I would see nothing wrong with chelating at very low doses. DMSA has saved me many times. I would wake up feeling absolutely horrible, and within a couple of doses start feeling better. Frequent low dose chelation is the only safe way out of this, along with antioxidant supplementation. Saunas or sweat baths are also excellent advice while you are waiting for DMSA to arrive. When I was very toxic, these would clear my head and I would feel almost normal for a while. Go ahead and chelate. At least you know you are getting the mercury out for sure.
