we only drink sports drinks when it's really hot or we've worked up a sweat cleaning or something.
our brand of choice is powerade, but there were not any of the one's we liked at wal-mart last time so we got gatorade.
gatorade is not as good as powerade, most of their flavors suck & the ones that are OK have a weak flavor. the only good thing is they are 32oz & powerade was reduced to 28 last year.
sport drinks are just sugar water with minerals to replace those that are lost in sweat, but it does seem to help. then again it could be all in our minds.
