Is there an easy and fast way to take care of diarrhea and nausea?

Clear liquids: Start with clear liquid like water, soda that is clear, or sports hydration drinks. Sip often to prevent dehydration.Work up to solids with bland foods like bananas, rice, applesauce, toast, gelatin, or chicken. Avoid alcohol, nicotine, caffeine, dairy & high fat foods. Consider adding in ginger via slightly flat ginger ale or ginger tea to quell nausea. Rest.
