I can not afford most medications, so when I have nausea, i either use "the pink stuff" or I drink one of several herbal teas. Mint tea is especially good for nausea and it tastes pretty good with a little bit of honey. Mint has been used for centuries to treat all kinds of stomach problems, including nausea. Another thing that I use to treat nausea is licorice root which is where the black licorice flavor is derived. I absolutely love black licorice, licorice root tea and even just shewing on the end of a licorice root stick. Licorice root and mint are very affordable and have many healthy uses. I advise you to take the time and look it up
Hope that you can find some relief.
Best wishes,
