Same thing here. I have undx IBD (according to my rheumy), and he told me it's entirely possible that enbrel has been controlling the lower GI sx for the past 9 months. I know that I've never been as normal as I am since starting the biologics for arthritis. Now that I'm going off the enbrel for a long while, we'll just have to see what happens GI-wise. I believe it was Erin who was dx with cd when she went off of enbrel and her lower GI systems went crazy.
