For many people, starchy foods cause acid reflux. I know it seems backwards, but that is the case for me and many other people I know. Carrie's suggestion of a journal or log is an excellent one so you can find out what triggers acid reflux for you.
Another approach is to try food elimination. Try avoiding starchy foods, including bread, pasta, cereal, potatoes, and rice. Try it for a week and see how you feel. If that did not work, try eliminating another kind of food, such as the nightshade family (tomatoes, potatoes, peppers, eggplant) which causes many people digestive problems.
My last thought is you really want to find out the cause of your acid reflux. Don't just automatically take antacids UNLESS the appropriate tests have been done to find the cause. Acid reflux can be caused by too much stomach acid, then acid reducing approaches are appropriate. But acid reflux can also be caused by too LITTLE stomach acid. In that case, the cure is to increase your stomach acid (I had to do this, using lemon and lime juice as digestive aids). You can see that you really want to know the cause so you do not take the wrong approach for a cure.
It is also possible that your stomach cramps are not acid reflux and the cure is something else altogether. So finding out the source of the problem really is important.
