Welcome to Healing Well, IBSupersad! I am guessing that you have either Crohn's disease or ulcerative colitis by the medications you have tried and those that are being recommended.
Not many with either disease regularly post here. We do have forums for both ulcerative colitis and Crohn's. I suggest you post your question on one of those forums aslo to increase the number of responses you get.
