I have been using this chlorine dioxide for about nine years and it has been very effective for me. When I first used it, I was suffering from fibromyalgia for almost 20 years, but I was able to get rid of it in just six weeks. Then, when doctors told me that I only had six weeks to live just before my sixtieth birthday, I decided to get serious about using chlorine dioxide again. After three years, I am still alive and fit, and the three cancers that I had were gone after just six weeks of using chlorine dioxide water purification drops.
