I find your attitude a little troubling. I wouldn't "refuse" to do anything if I thought it might relieve my pain. I am not saying that eliminating wheat is the answer for you. I am just wondering if that kind of mindset isn't a little counterproductive in terms of experimenting and finding out what works best for your system. One thing with IBS is you gotta be willing to try, try and try again! Plus, it's not like I'm suggesting you cut out water - wheat is an irritant to many people, not just celiacs or IBSers. Even my healthy roommate complains that it makes her bloated and constipated. Wheat contains gluten, a protein which can be hard to digest. I have tested negative for celiac and yet I found white flour products are like glue in my system.
