Bowel rest: Start with 24 hours of fluids only -no usual food items. Then start the Brat diet. B for bannanas, rice, applesauce, tea and toast. This is a soft diet to let the bowel rest and heal itself. If you still have diarrhea can take Imodium over the counter from the pharmacy. If still having the runs see a doctor for stool culture and sensitiviy testing at the lab. Michigan water supply should be fine.
