... got a call from him and waiting to hear back. I've been on it since June of 2015 after an 11 day hospital stay for a terrible flare. I was diagnosed in March of 2014 (first flare, 85% of my colon affected - severe CD) and am 53 yo. I'm wondering if this means I'm building anitbodies, or if my body is rejecting it. Truth told, even with the side effects that were pretty bad the first 6 months, I've been in remission since December 2015. The past 4-6 weeks I have had very loose stools, some, most in fact just plain diarrhea. Not looking forward to his response. Funny I wanted to go off it when I went into remission. Now I'm afraid to go off of it because of the severity of my flares.
