I tried 100 mg. DMSA every other day and my symptoms kept getting worse. Then I found Andy's protocol and followed it. Using 50 mg DMSA every four hours around the clock for 3 days and 2 nights, I've had no negative side effects and I'm no longer chemically sensitive or tired all the time! It seems the constant low dose of DMSA in the bloodstream is what makes the difference. Deduction: Andy's protocol does work!!!

P.S. I also tried chlorella and it made me very sick.
