I don't blame you! And to be clear, I was not recommending it to anyone. Sometimes my reflux was so bad that a shot of vinegar was a relief by comparison. I did it one day in desperation and it became habit.

Happily, I don't have that reflux problem anymore thanks to my change in diet. Sooo ... after reading this thread, I tried adding a couple of teaspoons of ACV in my morning cocktail of magnesium citrate powder and a pint of water. It adds a very small, subtle amount of sour citrus flavor and, needless to say, goes down much easier. I just may have swigged my last spoonful.
