I know you were asking someone else, but....

I've developed a new theory Scott, as to the vomitting and diahrrea. Personally I think it has to do with acidity, yes, but not acidity from pathogens,etc. the acidity comes from things like stomach acid. I've noticed some people react and some dont, many of the ones who dont are surprised, because they feel they, too, are overrun with pathogens.
The vomitting and diarhrrea? It's a simple sign that your body is too acidic, vomitting from direct contact with stomach acid, diahrrea from contact with acids in the bowell, and you're right, time to shift to a more alkaline diet. But nothing more. Even if you switch to an alkaline diet, and are extremely diligent, like yourself, occasionally you'll still feel nausea or diahrrea because your body will still occsaionally create acid, whether from that one thing you ate, or that one emotion which caused stress and consequently created an acid of some type. The second day after I did 10 drops and got violently ill, I remember vomitting a yellow liquid which I thought was acid, and it probably was. After vomitting I felt much better. Pathogens and die-off? NAH, excess stomach acid? I think SO!
