I drink either distilled water or purified water (Ozonated, De-ionized, carbon filtered) and have been for 20 + years. I drink between 1/2 and 1 gallon of it per day. I have never had a serious illness or been or felt inexplicably ill. That the "empty" water depletes minerals and other necessary substances out of your body faster than they are replenished has been a subject of debate for years and years. I should have died from heart failure many times over from all those years working outside in the deep south and drinking gobs of the evil, deadly water after already sweating out 1/2 the minerals in my body. Obviously I don't buy the "good water is bad to drink" stuff. Water shouldnt taste like anything as far as I'm concerned.
