That's interesting. When I upped the amount of time I zapped and even started using 2 zappers simultaneously, I noticed my energy levels went up a great deal. But it did not do anything for hiv levels according to the tests.
But it is impossible for an AC zapper to change Ph and DC zapping only temporarily causes an imbalance since minerals are attracted to one of the electrodes and away from the other. So what you are saying is just plain ridiculous.
