I have heartburn every single day for the past few months. anti acids like gaviscon work well but why wont it stop?

Acid reflux: You most likely have a problem with acid reflux. It is often a long-term problem. I would recommend that you avoid any particular foods which give you problems, particularly tomatoes,onions, orange juice, and citrus fruits. Tobacco and alcohol also contribute. You might want to try taking Zantac (ranitidine) twice a day for about two weeks, to see if it helps. If it returns, see your doctor. Good luck.
