I am also vomiting, should i go to the hospital?

Depends on details: Healthy, young adults can get the stomach flu or food poisoning symptoms from time to time. A person will usually vomit until the stomach is all empty, which is why it is usually important to not drink anything for a few hours afterwards. If worried that one has more than just a mild illness, he can see his primary care doctor. If unable to reach that doctor, a patient may go to an ER.
