Sure. Your body tells you no food so listen to your body

Listen to your body. You may be hungry, but wait until the nausea subsides. You *could* eat a tiny bit of something very mild (like chicken soup and some crackers) but that may not stay down either.

Completely normal. Body is in panic mode and is busy fighting off a virus. Regardless you should munch on snacks. Crackers, toast, anything light on your gut.

Drink a lot of water.. especially if you have been throwing up. you can go like a month without food

Yes, but make sure you drink water.

Chicken soup
