Water being hard to digest? When it is a large portion of what we are made? This is a dangerous idea. Also, I'm not sure how vinegar would help GERD when all it will do is add more acid to the stomach. I do have one helpful tip though. If you don't like chlorine, and I don't like the taste, you can let it stand and the chlorine dissipates fairly quickly. I do this for my fish tank water and it helps a lot.View Thread
