I used to mix salt and lemon juice for a good salty drink and sometimes used vinegar when out of lemon juice, and sometimes tried vinegar, lemon juice, and salt together, a salt/sour craving that some who grew up in hot climates recognize, which is why salty pickled foods are so popular in hot climates.
I’ve played in numerous senior softball tournament where you might be required to play 3, 4 even 5 games on a single weekend summer day. Pickle juice was a favorite remedy for cramping.....
Haymakers punch!! Great stuff when working in hot summer weather.
I sip pickle juice, instead of a sports drink, during my workouts.
