I agree, my first thought was an absorption issue.
I have moderate UC and have always suspected some lack of absorption w/ my meds, but my PM doc does not think so, and my GI says it's possible, but he is not the one prescribing my meds....
I wonder if a pain patch might work more steadly for you since you would be bypassing the stomach. Goood luck
