I haven't received the Miracle-Mineral-Supplement , yet - it would just make sense that you would feel better after getting rid of parasites & all of the toxins associated with them.
Some of the parasites, you may not see with the naked eye.... bacteria, viruses, & all of that.
It may not be necessary to overdo it, though. I heard it's good to take iodine, too. The Miracle-Mineral-Supplement may deplete some from your body but I have to study it further. It may be good to take some things to rebuild your system after getting rid of the pathogens.
