Any success with Unisom PM and B12???

Renae
Spring Break is over tomorrow  (I teach Kindergarten).  Unfortunately since hitting 10 weeks, my nausea has increased a lot!  I'm miserable, but I'm not vomiting much. I really don't want to do Zofran, but I also want some relief in order to feel better and teach all day.  Anyone have any success with Unisom PM and B12?? Constantly keeping food in my stomach isn't doing the trick anymore 😁.
