I do a lot of hiking and shit. every day, almost. so i sweat a lot, like i can wring my hair and clothes out, a lot

also I use a simple black tea and some lemon, with nothing else. From what my nephrologist tells me, it sounds like you have some sort of issue processing it.

That's horrible for your teeth. The odd acidic thing is fine but constantly sipping acidic things is really bad.

Chlorine evaporates. You can put it in a jug for a day, or boil your water.

Yeah, I tried everything, and simply, it has to be flavored enough to taste other than water completely. However, my iced tea is black tea, with lemon, and that is it.
