I agree w/ the above. The idea of drinking on the order of a gallon of water / day is to keep the garbage moving out of your system (flushing) & also keep things hydrated. Personally I like the idea of regular water w/ some orange, lime or lemon squeezed into it. The other stuff has "stuff" in it. Its processed. Granted I'm speaking in the big picture (it won't kill you to drink the flavored stuff) but I would make the larger percentage of water-like liquids regular water and the smaller percentage the 'other' stuff. To accommodate costs, I use a filtering water pitcher & keep it in the fridge. Cold water is better than warm water! I suppose you could squeeze some orange / whatever in the pitcher and let it "steep".
