Angela - Ask your chemistry teacher is she has the prescription Questran. This can really help people with diarrhea as a result of gallbladder removal. They're often misdiagnosed with IBS and once they're on Questran they have zero symptoms. She may have IBS as well, but the Questran could still really help her. If she has a computer she can log on to the boards here and post about this and I'll give her links to detailed info.
Best, Heather
