Open a can of Sprite or Ginger Ale & let go flat. After one hour, sip ONLY 1 Tbsp of it. If that stays down, repeat every 1/2 hour for 6 hours. Then follow the BRAT diet - bananas, rice, applesauce, & toast. Also saltine crackers, weak tea, chicken broth, Popsicles, & Jello. Only that kind of stuff for 24-48 hours, & only if it stays down.
