Because I have problems with swallowing water and am under doctor's orders to drink water or Gatorade/PowerAde and neither Gatorade nor PowerAde are listed. Would have been better to have an "other" option.
TheONLYPegasus: Gotta say that's the most interesting sentence I've read in a long time. Problems swallowing water? My nutritionist (I'm chronically ill) told me that Gatorade, etc. are loaded with sugar, if they threw some carbonation in there they could call it "soda" - really, check the label.....unless your a marathon runner or something similar that actually needs all those electrolytes (and burns them right off anyway).....
