Unisom and B6- overdose on B6?

Davesgrl2011

Hello!

My doctor told me to try unisom and b6 to help with morning sickness, and it just occurred to me that my prenatal vitamin has a lot of B6.... can I overdose?  I don't want to hurt my "little stranger", but I want desperately not to feel like I partied with Prince Vodka for the next six weeks.  Thanks!
