andy i read your posts and how you help people now i wanna help you too hopefully. i was wondering if you have tried pureed food diet say: brown rice pasta(better than the rice itself, more smooth) pureed & potatoes & carrots or any other vegetables pureed & fish/chicken for a few weeks to give your gi tract a rest from all the foods/pills. I heard it took someone 10 weeks of this diet to see improvement and that person was on caraf ppis and the whole thing which wasnt working at all until he started thsi diet. As for your GI pain have you looked into microscopic inflammation only shows in bippsies for ex: microscopic colitis affects all parts of the gi tract and can only be diagnosed with biopsy and maybe with enterolab tests thsi can also give u gastritis even gallbladder problems but its curable though you can find more info here:

unfortunately it goes undiagnosed for decades on the avg sufferer! bc again its microscopic and some doctors dont take biopsy of the colon...etc....just stomach sometimes!
anyways the guys on those forums are top notch experts i got a lot of help from em even though i didnt have mc or maybe i do i never had the biopsy.
i s7ncerely hope you get better have faith!
