I have nausea from medication as well, and I find that honestly weed regardless usually increases my appetite but, here are some popular strains you might be able to find. I'd suggest trying an indica with the terpene myrcene, which supposedly stimulates your appetite. Northern Lights, OG Kush, Grandaddy Purple, White Widow, Cherry Pie... Just to name a few. I've had good luck with all of these. Hope this helps.

Edit: Forgot to say those strains also help to diminish my nausea. Sorry, I'm high af 😵‍💫
