I've been following the Andrew Hall Cutler approach for chelating heavy metals and much of my Chronic fatigue and headaches are gone. He mentions that Alpha Lipoic Acid, DMSA, or DMPS with chelate Mercury from your body. Take small dose (25 mg) every 4 hours for 3-4 days then take 4-5 day break. It will take many rounds to get all the mercury out. Your amalgams must be out of your mouth before you do this. Before chelating with Alpha Lipoic Acid using his method and supplement ideas, I could barely get off the couch. Now after a few years, I am much more active and don't need to take naps anymore. Also, no more daily headaches and migraines only every 2 months instead of a few times a month.
