Carafate is a drug used to treat duodenal ulcers, is that what you have????
DGL licorice (let's please use the right form of licorice, not just any one) works like ZANTAC, except it's not a drug. It's a natural supplement that should be used to heal the esophagus and then stopped.
As I wrote many times, it worked for me. I am totally GERD free and no longer use the DGL licorice. It took one month on a very careful alkaline diet (not apple cider vinegar either) using the DGL 20 minutes before meals. I needed 3 tablets each time.
