The most important part of treating someone with vomiting and diarrhea is keeping the person well hydrated. Use this solution – basically, a homemade version of Pedialyte – rather than plain water to keep electrolytes balanced and prevent dehydration.
4 c clean water
3 Tbsp sugar or honey
1/4 tsp table salt
Mix all ingredients and blend well (works best if the water is warm). Powdered drink mix like Country Time Lemonade or Tang can be used instead of the sugar or honey, as long as you make sure the powder contains real sugar and not artificial sweetner.
Yield: about 1 quart
