YES! They are high in protin/ Very good for you also a little salt on them will help if you have been vomiting. Sodium reduces acids however they can dehydrate you so drink plenty of clear fluids.
The one who said he/she wouldn't eat is wrong. I had a gastro bug for more than a week. I hardly ate anything at all. My acid reflux shot right up. I ended up in the emergency ward yesterday with severe dehydration.
Cooked eggs yes but not raw. Scrambled egg for example is aid to help 'bind' loose stools so it will be good for you to do this.
Yes the are they can help fill you up but it's not to heavy on your stomach
You can.... But don't know that you should... usually best to stay with clear liquids and maybe melba toast or saltine crackers to be easier on yourself.
I wouldn't eat anything
