I’ve also had issues with nausea. To combat this, I’ve  developed a number of tricks. One, try to sneak ginger into your diet. One brand of ginger ale that I drink is Zevia. It has real ginger in it, and it’s sweetened with stevia, so it has no calories. If you don’t drink Zevia, check the ingredients of the soda before you buy it. There are many brands of ginger ale that don’t have any ginger in them at all. I also use Iberogast, which you can find on Amazon. It doesn’t taste very good, but I like to put it in coffee, which disguises the flavor.
