If you have just vomited, it is best to take a break from eating. It is important to keep yourself hydrated by drinking small amounts of clear fluids such as water, or tea or a sport drink with electrolytes and let your stomach rest without eating food. Avoid caffeine and fizzy drinks with sugar. Drink cool or cold liquids to help with nausea. As time goes on and you are able to keep liquids down without having an upset stomach, you may start eating soft bland foods such as toast, rice, bananas, or applesauce. Eat slowly and avoid greasy and acidic foods. Follow-up with your medical provider if your symptoms are getting worse or not resolving.
