If you're looking to go the natural route, ginger has always been my go-to for nausea. Ginger ale or there's a candy called gin-gins you can try. I keep candied ginger in the pantry and just cut off a tiny piece as needed.If you've tried everything else under the sun and nothing is helping, you may want to look into medical marijuana if that's an option where you are. My sister's best friend was so nauseous when she had cancer, she couldn't stand to eat anything for days at a time, even with prescription meds. Her brother knew a guy and well... marijuana made it possible for her to eat and keep the food down.
