Steve -- This is folklore so heed with caution, but you might find as I did that the pain is caused by a lack of acid rather than an excess; i.e. your stomach is too alkaline. Try a tablespoon of cider vinegar (real stuff, not a cheap fake) in a glass of water three times a day for a week. If you get gyp after the first dose, desist, of course.

Oh, and call me in the morning.
