One thought may be to go on liquid diet (chicken broth, vegetable broths) for full week. Clean out the ol' system. Eliminate ALL carbonated beverages (will produce much bloating) and only drink water. This will probably elmiinate all bloating for you and certainly clear out everything. Keep away from carbs (another bloater, doc told me anything with yeast should be avoided...think of yeast rising and stomach bloating rising...). Slowly add back in ONLY pure foods and smaller balanced meals (protein, veggies). See how you do with that for a few days. If you can get a food allergy test, do so. That may help you. Baby steps...good luck!
