I've taken Miracle-Mineral-Supplement /CDS and finally CDH for what I'd call a very challenging condition. That being said, my observations on effectiveness were as follows:
MMS: Highest effectiveness per dosage, highest persistence.
CDH: Decreased in effectiveness per dosage, good persistence.
CDS: Lease effective per dosage, little to no persistence.
Having said that, I found Miracle-Mineral-Supplement to be a very harsh treatment to tolerate. ie, The sweet spot for effectiveness seemed to be at/or around 19 drops, taken 3 times per day. To which I'd add, anything less would allow my symptoms to return.
