When I first got pouchitis, the antibiotics worked (metronidazole) worked within a day or two. As the years have gone by they don't seem to work as well and often I end up with C diff. at the end of the first antibiotic. I have to mention Ibuprofen....since I stopped using it I have not had a pouchitis attack.
Hope your vacation is great!!!
