I've had acid reflux off and on for over 10 years. If you have acid reflux, the pain would be in your esophogus as well as your gut, because the acid leeches out of your gut into the esophogus and is extremely painful. I've been taking prilosec for a long time, but not as much anymore. There are possible links to osteoporosis with this OTC drug if used frequently. I recently started using Maalox again - they have a new version out called Maalox Advanced for acid indigestion and heartburn. If you start to feel pain in your stomach, the best thing you can do is take medication right away before it gets into your esophogus, because thats when the pain really starts. Good luck and I hope your attacks remain infrequent! If it helps, its not an uncommon problem.
