Your diet seems decent enough. Although gluten free for 2weeks wouldnt be long enough, You'd need to go 6 weeks to clear your system out. You must be very frustrated at this stage and you have my sympathy for that. I know the eating for IBS diet has worked for a lot of other people but it obvioulsy isnt working for you. And I know as a result of this you probably spend a lot of time and energy trying to come up with a solution. I mean anybody in your position would do the same. But im wondering if its become such a big deal in your life that all you do is worry about food, stomach cramps or whatever??? Look your diet seems very tightly controlled, and i beleive you when you say youre damn healthy, but maybe you have things too tightly under control and that maybe you spend too much time looking for answers? Can I ask you a question, do you have somebody to talk to? What I mean by that is do you have somebody who you trust completely who you can be yourself with and who you could tell anything to and all they'll do is just listen? I maybe off with this but im not sure your problem is a diet related one and maybe youre looking for answers in the wrong places. Im sorry if what im saying is completely off base. On the physical side of things, I know youre probably sick of reading books or articles or whatever, and i understand that, but my suggestion would be to read "improve your digestion" by patrick holford. Its very short(about 160pages)and his recommendations dont involve ridiculous food combinations or require you to have a degree in the cullinary arts. Its basic common sense stuff. I'd knock the white rice on the head aswell and maybe eat quinoa or brown basmati rice instead. Hope thats some help Good luck
