Licorice (not the candy, but the supplement found in the drug store) has completely stopped my acid reflux pain. Whereas I used to have such frequent, and intense pain, that I wondered if I was having a heart attack, licorice capsules has eliminated them.
I empty two capsules into a cup of hot water and drink as I would a tea. And, it has the added benefit of tasking really good if you're like me and like the taste of licorice.
This worked when Mylanta, Pepcid AC, and a number of other over the counter pharmaceuticals did not.
