Sea bands for Morning sickness

Kelsey • Mommy to a beautiful 5 year old little girl and handsome 3 year old little boy. Another sweet Baby boy coming in May!
So, I'm only 7w3d and the past week has been awful awful with morning sickness. And it's all day long. It's keeping me from working. I took zofran with my first two pregnancies and that is obviously not a safe option any longer. Has anyone ever heard of sea bands? If so did they work?
