Don’t buy LaCroix. Buy something like a Soda Stream and make your own seltzer. I go through about 2L of seltzer a day, and making it myself (plus buying some calcium chloride, magnesium sulfate, and potassium bicarbonate to make my own mineral water) has been pretty rad.

Does anyone have a way of adding flavors to it without syrup or any sweetener (similar to la croix)? I’m fine with it plain, but I know some people prefer having a bit of lemon or lime flavor.
