I will say I don't give the bicarb approach much credence, but a few guys have posted that they were trying it. Since it clearly isn't a money scam, someone somewhere must have had good results. We didn't hear any more from them. Not sure if some of the reactions from the board ran them off, they are reading but not posting, or something worse. Maybe they will respond here.
I have tried the alkali water at the insistence of a friend who is a firm believer (Terry will scream - he wasn't happy when I asked his opinion, and at the costs of the machines, this might be a scam), but while on it my PSA doubling went from 90 to 74 days. If it works, I hate to see what would be happening if I didn't try it. I'm preferring to think it didn't do much.
