I felt like VSL III was a waste of money as well. I was tried on it a few times, cold turkey off antibiotics, and it was a dramatic fail.
I eat all kinds of yogurts, but I like the Yoplait lowfat probiotics yogurts, Noosa, and Chobani. I eat a yogurt for breakfast and another one as an afternoon snack but with the snack yogurts I stick to 100 calorie or less with low sugar and fat.
As far as the MRI Enterography, it's much better for diagnostic purposes than the Prometheus test because it also isolates the location of the inflammation especially up the pipeline so to speak. It's an almost 3 hour test and I posted a thread about mine here:
I posted that thread over 5 years ago and I am glad I did because I don't remember the details so well and that thread served as a journal of my experiences with the MRE. Right when that test was done I was at my worst point in the 25 years of managing the pouch issues and things have been much better since then with vastly improved diet and Remicade starting in 2015.
