For me, eliminating grains, sugar, yeast, actually all processed foods for a time helped me tremendously. I now only eat those foods in moderation. You may have a yeast overgrowth and the foods you are eating (grains/sugar)are feeding the yeast, causing your symptoms. If you can't go cold turkey with changing your diet, try eliminating all foods with yeast (what does yeast do to bread?) and all grains for a while. Sugar can be a trigger, as well. Do you eat artificial sugar? That is generally a no-no for IBS'ers, as well. Peppermint tea or hot water with added peppermint oil (found in baking goods aisle in the grocery store) can help with the gas and bloating. Good luck!
