I'm starting to doubt sugar free electrolyte mixes. The sugar matters since it carries salt and water to frankly the gut for absorption. Gatorade, made for athletes after extreme exercise, frankly is loaded with sugar. It shouldn't be a basic hydration fix, but there's a reason for the sugar (besides the addiction lol). I don't do this nearly enough, but you get the electrolytes you need from 16-20oz of water with half a tsp of sea salt, a squeeze from a quarter lemon and half a tbs of honey.
