I think it's the Imuran. I am taking it and sound just like you... it's finally clearing up my UC and I'm feeling good in that aspect but I'm just so tired. And it's not really an "I'm tired I could sleep all day" type, it's more of an apathetic, lethargic feeling. I have to force myself to do so many things. I am in Chicago in the middle of crappy weather so while I think that isn't causing my fatigue, it certainly isn't helping! Sunshine hurry up! :)
