I drink maybe 1-2 beer a month. I used to try to avoid bread because of carbs but i have not found that makes a difference. Spicy foods are bad, dairy products too. I do limit those but i eat some on occasion. I gave up soda, mostly gave up rum ( but i need some in my egg nog for Xmas). I have been trying to cut back on sugar as well. It is hard. Even catsup has sugar in it. Sigh. Maybe if i just ate white rice, fish and veggies i would feel better.I have IBS too. I can definitely relate to the pain. What used to be what triggered mine the worst was yeast. For some reason it doesn't seem to trigger it anymore. Maybe try cutting bread (and beer if you drink it) out of your diet.
