You might check out the alkalising drink at ASK MOPRELESS FORUM.
Also, do some research there regarding food quality, high brix foods, pH and ask for some help there.
More success stories there than anywhere in CZ, as far as I can tell!
BTW, not all ACV is equal. Poor quality will do bad stuff to anyone who lacks enough of the full buffet of alkaline minerals in their system to react against it. Dilution does not improve the quality, just reduces the harm being done.
