I’ve tried low FODMAP, low inflammation, all sorts of stuff. The only thing that ever worked for me was seeing a Chinese herbalist. I did a really strict diet for a month that was a lot of soups, low oil, low spice, and cut out all alcohol, caffeine and processed foods. After I did that for 4 weeks I had my only normal BMs for years. Unfortunately a diet that strict is really hard to keep up when you’ve got a family and social life.

The only meds I take are pepto bismol and that’s just for travel to keep my symptoms more managed

Unfortunately, I do not have any answers, but I wanted to throw out there that I am finishing the elimination phase of the low-FODMAP diet, and it has left me struggling to feel full while still facing daily symptoms (maybe not as bad as prior to low-FODMAP, but still interfering with my daily life). So I understand your stress!! I wish you the best of luck with finding better solutions!
