Your choice is between forever living on a horrible diet or once a month zapping for 30 minutes. I had candida for decades trying diet and pills and very unhappy with it all. I agree with you that the sitess selling Clark Zappers are mostly scams. They claim a lot but offer no proof. The Candida Zapper is a specially modified Clark Zapper that was proven effective against candida in laboratory tests. Effective in this case means it completely killed it. Why then retreat every month? Because candida spores are in the air we breath and on the food we eat. If you have a candida infection it is because you have an immune weakness that allows it to grow. But doing something easy for 30 minutes a month is way better than avoiding all simple carbohydrates. http://www.dragonfly75.com/eng/CZ.html
