My reaction to vinegar.. It dried out my esophagus and made it burn so bad that I could not stand it. It took 3 or 4 days to get the burn to settle down.
Now, if I even try just a little vinegar, I start getting a burn there. Not as bad, but then I have never tried more than a little taste since the first time.
There are a lot of people that swear by the vinegar.... You could give it a try and if it affects you in any way... stop.
