Unisom, Seabands and B6


I'm miserably nauseous and throwing up multiple times per day. Called the OB and the nurse recommended trying B6 with Unisom. I'm wondering how much Unisom to take and of course the office is closed to ask now. Anyone have luck with this? Also, the nurse said the Unisom will knock me out but I'll build up a tolerance eventually. Trying Sea Bands too. Anyone have luck with these? I need to eat and drink. :(
