Hi, Guessing you were using the first book for your dosing mechanism, as for the last year or two we've been using protocols that use small drops (3 drops an hour, once an hour, for 8 hours a day) - not the three BIG doses a day.
We also state that if you are having problems, you might consider what we call the baby bottle technique, where you start out with an 8 oz baby bottle and 1 drop taken over 8 hours, so you start at 1/8 of a drop an hour. You will always need at least an ounce of water for every drop of activated MMS.
Also, there's a new activator - HCl which can be tried.
And CDS - sometimes people have issues with the citric acid - CDS does not have citric acid. Some of us find CDS a lot easier to take.
There's a lot of information available here on the forums about these things.
As I understand it, stablized oxygen does not use citric acid, therefore it's actually not "similar to MMS" - as I understand it, you'll have to read the bottle, and it may be sodium chlorite - (and I don't know what percentage of SC) - but it is not acidified, which means it would depend on your own stomach acid to become acidified - to release the chlorine dioxide. And if your digestive system is less than optimal, you are not getting the full "advantage" of what is there.
