I haven’t used CBD personally for nausea. It was suggested not to use it because of potential interference to other medications I was on. I have heard from other acquaintances that it worked very well.
We do have a number of members in the forum who have used CBD for nausea.
I did a quick search and there are several pages of references for you to peruse through. Type in, CBD for nausea up in the search bar and you’ll get a listing of all the conversations.

What are you currently taking for nausea? I had 3 meds but the most appreciated were the little Zofran sublingual melts.

I know it’s awful trying to find foods that are even remotely appealing. There’s a great website you might be interested in checking out. Cooking for Chemo. Chef Ryan has some really good recipes that trick the non existent tastebuds. 😅

Are you nearing completion of your chemo?
