My conclusion is, that when you first take Miracle-Mineral-Supplement , it taxes the body until you build a resistance to it. This usually last a few days and most often comes in form of extreme lethargy. Though it can be accompanied with a host of other symptoms such as; headaches, bone pain, loss of concentration etc. My wife for example would get a headache.
There has been much speculation attributed to this particular side-effect such as ; a herx reaction or die-off. However... it has been my observation that even healthy people would undergo these side-effects as well, and so make of it what you will.
All in all, I'd say Miracle-Mineral-Supplement can be likened to a harsh form of treatment. And so I wouldn't recommend taking it for all but a last resort rather than the so called preventative or maintenance dose type uses that are sometimes mentioned by websites or individuals.
Aside from this, it has been my observation that the use and ingestion of Miracle-Mineral-Supplement impacts various things such as electrolytes, and minerals. Particularly the magnesium, potassium and iron. Though what we don't know, is how or why this happens. ie, are these the result of changes at the cellular level or as a direct result of the chemical interaction with the digestive system or bloodstream?
As for MMS's effectiveness, I'd go as far as saying that MMS did what no Antibiotic or other drug could do in my own case. And that was to stave the effects of a chronic bone infection for several years. Of which, I took large quantities(19+ drop equivalents) of MMS 3-4 times per day, everyday for nearly 4 years. To which I'd add, I did not die, develop cancer or form any tumors etc. Though I think it's worth mentioning that I did struggle with impaired kidney function for nearly two years following the cessation of MMS products. To which I'd add, I have no way of knowing if there's a connection between the MMS and my kidney problems given that the type of infection I struggled with is not only known to impair organ functions but more importantly, kidney function. - However, I figured it is worth sharing for the sake of record keeping given the seemingly sparse amount of data attributed with long term use in humans.
In the end, I switched from MMS to CDS and finally CDH(alternate forms of MMS) in the final 1.5 years of my use. Until I discovered Colloidal Silver along with a none invasive Blood Purification system and haven't looked back since. Not saying MMS wasn't useful. I maintain to this day, that it saved my life. And keep a fresh supply of CDS on hand for emergencies which we(our family) continue to use topically with great success. Though it worked-out that the combination of Colloidal Silver and Blood purifier proved to be far and away, better than the MMS ever was in my own case. - Better tasting, fewer side-effects, and much easier to make, store and use.
Hope this helps.
PS. After taking MMS for years , I reached a point where I could no longer tolerate the smell or taste. It got so bad at one point, that I would throw-up from the faintest smell or taste. :/
