Carolyn, you can't buy Miracle-Mineral-Supplement (chlorine dioxide) in a store. Get it here http://www.mmsdr.com/.
Click on Shopping Cart button to get to the products. I don't bother buying the citric acid activator. It's cheaper to use ACV (apple cider vinegar.) I also got some of the silver solution product for the candida (it gets weakened by Miracle-Mineral-Supplement , but does not die, and does mutate, but the silver then kills it. Use it during the third week, I think.
Lots of info about protocols here http://jimhumble.biz/
and how to use it. If you get in, it's a good time to get in because the protocol now is more effective (going from 3xday at higher doses to many times a day at lower doses.)
It's cheap as dirt, it tastes kind of lousy, but it seems safe (it's not Chlorine), and I think in combination with Hulda Clark 's herbs you would see the results. The trick to this is identifying what is getting eliminated. Otherwise you might never know. I got lucky because I fast and do irrigations before a flush so I could observe what was going on. They are so fragile and slimy and whispy that I'm sure nobody would notice them if the water was not clear. I did. When you see hundreds of dead beasts floating in the water you have no doubt. A lot of them look like globs of "something" with tentacles or roots. You might check out the photos of them to get some idea what to expect. They generally don't win beauty contests, eh?
