I have a stomach virus, what to do?

See answer: Stomach viruses (viral gatroenteritis) are common and usually go away with supportive care. Drink clear liquids (starve a virus) for 18-24 hours, than slowly increase your diet to soft "brat" diet, and as tolerated, you can slowly increase to a regular diet. Nausea meds may be helpful too. Usually, in time 1-3 days, you will feel better as it runs its course. Best wishes.
