I have acquired NDI as a result of taking a prescription drug and not being told of the possibility of permanent, untreatable and irreversible side effect of NDI. Lately water, critical to all forms of life and especially critical to someone with NDI, has actually been dehydrating me due to the metabolic acidosis resulting from the dehydration and ongoing electrolyte imbalances.  I am searching for someone who has insight into the science behind the effects of differing pHs of different waters (purified/reverse osmosis=low pH, naturally alkaline=higher pH, RO + electrolytes=even higher pH) and how to get some kind of homeostasis back to my body!
