it MIGHT have to do with the ACV (not sure)
I just posted this to another message, here is the copy, maybe it will help some:
"... I think it might depend ot the body type... some people tolearate ACV, some do not.
I never used anything else but the lemons with the
Miracle-Mineral-Supplement , as I love the healing qualities of ACV, but from my past experience, I know it always made me feel queasy and nauseous in itself... so I was not even bothering trying it in this protocol
You can buy fresh squeeze lemon juice in Whole Foods or most of local Natural Food stores, but if you cannot find any, then do what someone else already said, just cut the lemon in half and use it that way, it's the simplest.
(And no, you don't have to count the drops each time, just figure out, how many drops per teaspoon, I think it is about 80, but not sure, and then use that much, plus I always add little bit more, just to be sure I got enough :)"
