To answer your question, Bill, yes, everything makes sense to me re: mms1 and CDS. I think a number of people have stomach distress (whatever those words mean to them - cramps? diarrhea?) - and as long as bicarb does not interrupt the action of mms1, it may be a working alternative. We add the acid to the SC to bring the ph back down, so it's not too alkaline, bicarb raises alkalinity in the body - may be something to watch, there. But, it makes common sense - and a lot of mms, whether mms1 or cds is "common sense" based, as I have seen it.
In my case, it wasn't stomach problems or "taste" that could be covered up with sweetener - or even juice - it literally was the gas getting up in my sinuses and making them hurt and me nauseous. So, for me the CDS has been a real blessing. I even use it for my teeth - however, I keep my skin spray solution in mms1 form, because I keep some of it in the bath cabinet upstairs - and although that room stays around 60F, it's still a little warmer than I want to keep the CDS.
A number of people will stay with MMS1, some will go to CDS - I think we'll find that those who go to CDS will do so because they CAN'T do MMS1 - after all, if the choice is no treatment at all.... vs treatment you can do, I think that those who believe in Jim's work or have experience with it, will go with what they CAN do.
