Stay Hydrated :
When you have been vomiting you tend to get really really thirsty, but do not drink water. Water makes you vomit more as it is poorly absorbed by itself. Gatorade, pedialyte or other electrolyte mix, juice and soup broth have a much better chance of staying down and actually hydrating you. Ginger tea and ginger ale are notoriously good at calming an upset stomach, but remember to sip small amounts at a time.
