Had norovirus two days ago and havent felt same since, ate for a day then puked the next, gas and acid are present, take zofran for nausea and vomiting and pepcid ac for acid and reflux, now i have sulfur burps, what should i do next?

Hydrate, hydrate, hydrate!! Most of the reason that people feel so poorly after viral gastroenteritis is dehydration. You will recover from the virus, but you will feel much better along the way if you’re able to get to the point that your urine is almost colorless. You can also take out acids if you are having acid reflux. See your doctor if you are no better in four or five days. Good luck.
