I am interested what the atrpine did for your diarrhea??? My father in law was fine following the whipple but in the last couple months has been really struggling with diarrhea/stomach pain/maintaining weight and now back pain (which may be an old injury...they have checked him out..i.e. bone scan, chest x-ray etc.). We will try anything that might work for his stomach/diarrhea. He is on enzymes already but that is all anyone is suggesting...Any suggestions or ideas. Thanks for the info and inspiring stories.
