Also try to drink something like Ensure. I had to do so bc I had no appetite for my first few months and needed the extra nutrition.
Well don't keep eating... Start with liquids... Water,gatorade,sprite, or gingerale. Try jello as well. Then slowly move to the B.R.A.T. diet. (Bananas, rice, applesauce, an toast) basically all bland foods. Biggest thing is staying hydrated.
