I have a medical condition which will be tough to treat, and it means the end of radio (for now)

Mumbles, why do you say I shouldn't drink commercial Alkaline water?

one reason, regardless of effectiveness, is that your tap probably already gives you fairly alkaline water. The MWRA, our local water company around me, treats the water to a pH of ~9.5, because acidic water is far more likely to leach metals and toxins from the pipes, but alkaline water will not.
