it had worked really well for me. Just remembered it last night and dug up the mix:
2 quarts water
6 tablespoons honey powder (you can use honey, but honey powder is a bit easier to mix)
2 teaspoons Himalayan pink sea salt
2/3 cup lemon juice (if you prefer another citrus juice, you can use it instead)
1/2 teaspoon orange extract (for flavor; without it, the taste is fairly blah)
That's the original. Over time I changed a couple of things:
The sea salt has some other minerals in, I'm told, but plain salt seems to work. And you can do something else: use half salt, and half Morton Lite Salt, which is half potassium.
I'm only using 3 tablespoons of honey, seems to be plenty.
Can also use orange juice or lime juice, big factor is some type of citrus.
