HOW I FOUND ROCK SALT, WAS WHEN I WAS WORKING AND MAKING TOYOTA CARS IN FREMONT, CA.  THE LINE OF CARS WOULD GO REAL FAST (ABOUT 350 CAR A DAY), I DID NOT HAVE TIME TO LICK SALT.  I BOUGHT SOME ROCK SALT AND FOUND THAT WAS JUST AS GOOD AS LICKING SALT. NO ONE KNEW I WAS EATING SALT.  YOU MIGHT WANT TO TELL YOUR DAUGHTER TO TRY IT.  THE  BOSS DON’T NEED TO KNOW SHE HAVING SALT.  I WOULD JUST PUT IT IN MY POCKET AND POP IT IN MY MOUTH.  ( BY THE WAY TOYOTA CARS , TRUCKS, AND VANS ARE  AN AMERICAN MADE FROM THE ENGAIN TO THE DOOR PANELS).

MAY GOD BLESS YOU.
