<human>:  What is the best thing to do if I get a stomach bug?
<bot>: The best thing to do if you get a stomach bug is to rest and stay hydrated. Drink plenty of liquids (such as water, sports drinks and clear broth) to replace the fluids lost through vomiting and diarrhea. You should also avoid foods and drinks that can aggravate your stomach, such as caffeine, alcohol and spicy or greasy foods. If the symptoms are not improving, you may need to see a doctor.
