What is best to end two days of diarrhea?

Diarrhea: Follow a bland diet and avoid harsh roughage like raw vegetables,salads,nuts, skins of fruits,popcorn,etc. Drink enough room temperature fluids and take kaopectate as directed. Imodium (loperamide) is stronger and can be taken if needed. If the cause was a viral infection or reaction to food, symptoms should resolve in a few days. See your physician as needed.
