There is a SIBO/Rifaximin dosing clinical trial taking patients until May 2006 in Cincinnati. Have to have had a colonoscopy or sigmoidoscopy in last 24 months and be available for weekly appointments for up to 17 weeks(nothing invasive after the colonoscopy). Also, the study will pay for the colonoscopy. I met one of the people running the trial today at my new GI and he seems pretty knowledgable. He seemed very impressed that I had heard of Dr. Pimentel. I have IBS-D (sometimes A), and he thinks I would be a good candidate.
