Hi (by way of introduction, I had been one of the original posters on this forum - then I lost track of it - as well as my pen name at that time, but now I found it again while searching for info re: PCA-Rx. At the time, I had PM'ed Laura re: my amalgam-removal trauma).

Since then, I've travelled a long way, & I decided to put in my 2 cents here because I, too, am allergic to acids & citrus. Note that on the PH scale, sulphuric & citric acids are a lower PH than vinegar. I'm not sure where ascorbic fits in on this scale, but it may be something to consider. Also, it's my experience that black cherry, raspberry, even maybe acerola , as well as magnesium & potassium make for very good protective buffers against acids. On the other hand: Phenolic/grape & malic/apple acids can be quite harsh on me, because they have an added, scouringPowder type of ingredient in them. Ditto vis-a-vis cranberry and pomegranate.

But above & beyond that, is my theory that the more extreme the stimulant is (i.e. either very low PH or very high PH), or even fluresent radiation emanating from computer monitors - all these may cause CALCIFIED-NANOBACTERIA & LYME CYSTS & HEAVY METALS to get stirred up. And because they have calcified shells surrounding themselves, the calcifications can tend to irritate whichever bodily organs they reside in. Which explains why pain travels. BTW, computer monitor emanations & citric acid & other "harsh-stimulants" (by stirring up internal toxins) can trigger them to cause headache, nausea, dizziness, eye inflammation, bone degradation, tooth tingling, etc. etc.

Also note that MANY people are getting helped by the Salt/C protocol. I strongly suspect that's because it somewhat mimics EDTA & sodium-citrate chelation, as was researched in the 1970's by Sincock as having an anti-aging effect. I suspect the Salt/C chelates calcifications, then zaps the various parasites that tend to burrow inside calcifications.

P.S. Note that some people tack on even more "C" or citrus to the Salt/C protocol.
