The things I do to cure any ailment now is to fast for long hours specially when my pouch is rocky. The butt burn, excess gas and cramp in the stomach I had them all . I am sure it was pouchitis. But I didnt want to go back on antibiotics ever so I fasted for 20 hours straight. I wouldnt say it all healed up in that one time but I was relieved. I do intermitent fasting upto 14 hrs so thats helping this alot. Also I eat loads of bananas when I have a rocky day. I'd hate to say it but stay away from high lean protein source for a while , they tend to be gassy. I'd try and reduce it to 3 meals a day, 4th one if you workout. That will give your pouch sufficient rest. And Imodium causes constipation very and loads of gas. I take 1 tablet in morning first thing with my probiotic and pysillium husk.
