I remembered your telling me you visited Mass. it's a shame you're not still here. My doctor is wonderful. Head of the department at Brigham and Women's in Boston. And I was so sick this week (they think I have a parasite this time) that he told me to see my PCP and that he'd squeeze me in next week between patients.
The "good" IBS doctors understand at very least about soluble fiber and possibly muscle relaxants so that you don't feel "flare ups" with as much force.
I agree with everyone else who tells you that you should definitely find a new doctor. It took me several tries to find the one I have, but I wouldn't trade him and his knowledge of this disease for the world. Karen =)
