I went through something similar around Thanksgiving - sounded like norovirus when it started, but then was lingering. I too was worried - and sure enough a flare started. When I looked back, I wonder if I ever had the virus or if it was just the onset of the flare - no one else around me came down with it! Hmm.
Between my GI and the kind folks on this board, we were able to get it under control quickly - I went back on VSL, and also started doing canasa each day and rectal hydrocortisone each night. I also added in colostrum, which seemed to help as well. I ate lots of bananas, deli turkey, and sweet potatoes! Good luck - hope you feel better in time to celebrate.
