I live a pretty hectic life so staying hydrated is always tough. I bought these in hopes that they might help with balancing out electrolytes and make me feel less thirsty. I bought the Strawberry Lemonade flavor, although it tastes nothing like strawberry lemonade (it tastes like a cross between a tropical fruit and artificial sweetener). Despite the flavor, however, I have to say that I like the results. After finishing 1 tab I already feel more hydrated. You can find Nuun at Whole Foods for $4-$5 a tube.
