Doug,

Have you checked with any medical doctors about this? It seems to me that same chlorine or iodine that will kill bacteria and microorganisms in the water will do the same thing in your digestive tract. I would think that this could lead to stomach cramps, gas, or diarrhea. Speaking of which, is everyone packing Pepto Bismol and Immodium in their first aid kits and T.P. in their survival kits?
