Well if you have a 1 gallon jug or pitcher. You add 1 cup granulated sugar. 1 tablespoon of salt(iodized if you want the iodine) and you add whatever else to it as you like for flavor. Be warned it tastes just as you would expect and I normally do it another way.
8oz glass filled with filtered water + pinch of iodized salt + 1 tablespoon sugar. Let dissolve and drink. It also can be a glass with sugar. Drink the whole glass with the sugar alone and eat a pinch of salt. Goes down easier that way too.
Never use those squirt flavor things. That stuff will kill you. It has splenda and other garbage depending on the branding. Those are dangerous. Like diet soda having aspartame in them. Dick Chaney (yes, the ex vice president) bought the company that was going under and aspartame was the only product they had. The folks that made it told the bastard it was poison and would kill people and he passed it through FDA restrictions anyway as a “diet” key part is the DIE lol
But seriously, nasty stuff.
