Why not just drink cold water? In Norway they sell water with taste added. The problem with some of these is that there is sweetening crap/sugar in it. You might not taste it all that well, but it's there. And sugar, like salt, makes you thirsty and dehydrates you. I'm sure they make them without sugar too. Personally I prefer drinking water as it is, with as little weirdness in it as possible. Not sure why everyone insists on only drinking/eating what is bad for them..
