answer:White rice. Bland bread. In small quantities. Only if no vomiting though. You mite could get some plain white rice from the place you got the egg drop soup, if you don’t feel like cooking. Eventually add protein, like unseasoned chicken or beans. Lots of fluids. Not watered down crap. Pedialyte, Gatorade, or coconut water would be rich in electrolytes (which you need.) You could just chug water, but it sounds like you need something with a taste. Hope you feel better. Peace n love
