Are ritz good for stomach flu. what is the best way to rehydrate after, and how can you tell if your dehydrated ?

May need a doctor: A person gets dehydrated usually from vomiting and/or diarrhea, especially if she is drinking incorrect drinks or amounts. Tiredness and thirst are early signs. Mouth then gets sticky (instead of wet), eyes look a bit sunken, urine is little and darker, hands and feet get colder, skin color doesn't look so good, skin feels dough-like, etc... Small sips of Pedialyte every 20-30 minutes helps.
