Give me all your non-typical nausea remedies!

I’m 11 weeks and have been nauseous and vomiting since week 5. I feel like I’ve tried everything - classic foods like crackers, sour candies, ginger, etc. Medications- diclectin (unisom + B6), Dimenhydrinate. I’ve tried eating frequently, never letting my stomach be empty. Nothing really seems to work. What worked for you that you haven’t seen other people recommend?
