I have eaten anything for the past 7hours since i have vomited?

Hydration: If you are not vomiting any more, make sure to drink enough water, fruit juice or electrolyte drink so that your urine is mostly colorless. You may eat as tolerated. If vomiting is persisting, you should go to the nearest hospital. Wish you good health!

Gastroenteritis: Nausea, vomiting &diarrhea usually are caused by a viral gastrointestinal tract infection or food poisoning.Associated fever favors the former. Both conditions gradually resolve after a few days. Rest up, drink plenty of room temperature fluids &flat ginger ale relieves nausea. Eat soft,bland,nongreasy foods. Kaopectate or Imodium if excessive diarrhea. Start eating saltines,broths. See MD as need
