Sore throat: These are signs of a viral illness, which typically last 7 to 10 days. When someone feels this nauseated, they should focus on drinking at least eight 8-ounce glasses of water a day first. Drink before you eat, and avoid high-fat or acidic foods to help decrease discomfort. If vomiting makes it impossible to keep down food or fluids, an immediate recheck is needed.
