You may: have a serious gastrointestinal condition and will need to be evaluated today. Good luck.

Rehydration: Not sure what your question is, but you either have food poisoning or a GI virus. In either case this will probably be over within 24 hours. The greatest danger is dehydration. Don't even try to eat but try to drink water- consider ginger tea with lemon and honey, can even add garlic. Coconut water with a pinch of salt replaces sodium & potassium. Vegetable broth can also replace electrolytes.
