This seems that you have got infection what you call as stomach flu most likely from the one day old food.Gastroenteritis is the irritation and inflammation of the digestive tract..This may last from several hours to several days and a prescription medication may be required.Take tab perninorm once a day to stop vomiting & nausea.Take tablet. Acetaminophen.To get relief from burping,take antacid- Gaviscon.It contains alginic acid and sodium bicarbonate. The combination of the alginic acid and bicarbonate will create a a foam barrier which floats on the stomach acid,providing great relief.Also take tab.Ranitidine(Zantac) 150 mg twice a day.All these are available without a prescription.
If this doesnot help in 24-36 hours or you have any major discomfort,then consult your doctor for the prescription medications.
