I just started round 5 of my toxic metal chelation. Sticking to 12.5 mg of DMSA every 4 hours. My kidney don't hurt on this round. My brain fog would usually worsen but it's the same. My hair analysis had shown that my levels of Lead, Cadmium & Antimony were at 4X the threshold of healthy ppl. The arsenic was at 1.1X. I also turned my little telephone closet into a sauna. Electric heater and my 250Watt heat lamp. I sit in there topless and work up a little sweat. I can smell the toxins coming out. Cadmium is very hard to chelate out but I read that sweating does take it out. My angina problems very rarely appear now and my memory is better. It use to be that I could transcribe a number by ONE number at a time. I could go to the garage and completely forget why. This has improved. My fatigue is the same, but Lead weakens the immune system so I'm still taking Transfer Factors and Tumeric for my EBV and CMV. Dr. Carol Ryser says that it can take 6 months before the body rebuilds itself and energy returns slowly during that time. I have an old house that I had sanded and completely repainted. I think that this is the source of my toxic metals...but I'm still searching. Canned foods are still soldered (solder = Lead + Tin). I now eat fresh or frozen.
