Best morning sickness products?

Anyone have some tips on products to use that helped beat their morning sickness? A nurse told me to get unisom and b6, and needless to say, they didn’t stay down very long. I haven’t been able to keep ANYTHING down today, not even liquids. If i don’t touch anything i’m totally fine other than being weak and light headed so i’m sure i’m going to need to get something down eventually just this pregnancy, it’s not happening.

Ive tried water, bread, crackers, popsicle, i have a banana now but i’m so tired of spending my day in the restroom so I’m hesitant to even try it.
