I am considering do a drug research for IBS "D" here in Ohio. I'm not sure what the drug is yet. Are the history and physical workup through? What all is involve as far as test. Are these research clinics caring towards their subjects or are you just an object being tested. I would like to participate and hopefully get a handle on this IBS even if I feel good during the trial if I get the drug. The way my IBS is I will probably get the placebo. I am interested in hearing what others have to say about this topic.Bill
