Hi Laura,
I am sorry you’re having so many issues. I have struggled with pouchitis similar to you as well.
I have found relief taking Xifaxin. Usually a two week course. The last time I took for 28 days. Then my GI doctor had me try Budesonide 9mg daily. Wow. What a difference. I eventually weaned off of the Budesonide about 8 months ago and have not had a problem since. Fingers crossed.
I do take VSL#3 twice daily and eat a pack of Metamucil wafers daily.
I hope you find what works for you. Take care.
