hope you are already better now.
The normal dose of budesonide (Entocort) for me was 3x3 mg per day. In the past years I reduced it to 2x 3 mg most of the time, since I took it for a long time.
The cipro is often taken together with Flagyl for pouchitis. If you are still having trouble that might be an option.
The other things you mention - well there's a lot one can try, but perhaps not all at the same time. Reducing sugar and alcohol is a good idea from my experience.
As you did't have a problem in the past years you can probably forget about the gluten.
If you are lucky you can get rid of inflammation with the antibiotics and carry on es before.
