I'm so happy to hear that everything worked out ok.
My DH suffered with severe ulcerative colitis, (he stopped taking his meds which included imuran, because he was feeling better!) after 3 years he had another flare up and nothing worked. In November he had to have his colon removed and now has a permanent ileostomy.
It is so important to take your medication (even when you are well) for these diseases as they can come back at any time and you can get seriously ill very very quickly.
