Thanks for your responses. I'm not flaring right now. So, I'm thinking that maybe it is the Asacol. I'm gonna follow quincy's advice and do a slow taper, 1/wk. If I start flairing, I'll go back up. I don't wanna tell my doc, though. I don't think she'll approve. It took 3 years to find her and meds that work! I gotta do something, though. I'm so tired all the time. My 81 y/o mother in law has more energy than me!
