You may want to try the "recipe" below. This was give to me years ago and it has worked great for vomiting for my family. It seems to settle the stomach and keeps you from becoming dehydrated. My adult children still use it!
For Nausea and Vomiting
1/2 Cup Gingerale
1/2 Cup Orange Juice
1 Tablespoon Karo Syrup (Light or Dark)
Mix together and give one tablespoon every ten minutes for six doses (if needed). Then give every 20 minutes until 2-3 doses are retained and nausea stops.
My kids continued to sip on it because it tasted so good to them! Hope this helps.
