I decided to use only Alpha Lipoic Acid for chelation on this round. Dr. Cutler says its OK to use it instead of DMSA. I used 50mg every 3 hours for 2.5 days. This was the nicest chelation round ever! The hard part was getting up every 3 hours at night. ALA is real good at chelating Arsenic and Antimony. Lead and cadmium to a lesser degree. ALA chelates intra-celluar. During the rest cycle is the time to evaluate any good changes and I can't report anything right now. Per the Yahoo forum: Adult Metal Chelation, most ppl don't feel much of a change until 9~20 rounds. My short term memory has improved. I know from a hair analysis test that I have Lead, Cadmium, Antimony & Arsenic. So, I chelate in hope of curing my CFS for good! On my next round, I'm going to try DMSA (12.5mg) + ALA 25mg, both at the lowest dose and see how bad things are. Dr. Cutler says that the combination works the best if the patient can tolerate it. Since Lead weakens the immune system, I'm hoping that if I can remove enough of it, that my white blood cells will kick into gear and start fighting Epstein-Barr and cytomegalo virus plus whatever else I now have.
