So glad to hear you are recovered and doing well. I had my dormant jpouch for a year while disconnected. I had some serious, unexpected and uncontrolled discharge as well - mine happened during the day, typically. While waiting for pouch removal, I was given Keflex in an attempt to help control the discharge. Keflex did help a bit, but I still discharged every day. After removal of the pouch, the discharge was gone, outside of a small amt. through a small opening the surgeon left for drainage. My pouch removal was due to fistulas and abscesses, not because of the discharge.
I don't know if over time the discharge will diminish - others may have more insight on that, as I recall there are some individuals here who have kept their dormant jpouches for quite some time. Good luck to you!
