Nope, but the classic pink prenatals often make women sick. I'm getting mine from optinatal this time :

That drug they give women who have hyperemis gravardium (??) is essentially half an antihistimine and half a b vitamin. I've known moms who make their own that way when they could not get it prescribed.
A B vitamin before bed (or in the morning, if it's worse at night) will quell m/s. Getting a better prenatal will quell it. Not eating crappy food will quell it, even if you crave it.

Last time I didn't eat as well as I do now. I ate a lot of refined sugar, and didn't balance my meals well (I'm vegetarian now, wasn't then). I had it really, really, really bad. All day long, all night long. It was terrible. I didn't get it until I was around 13 weeks though, so I don't know how well I'm preventing it as of yet. But at least I have confidence that I am eating a much more preventative diet.

Last time I lived off tums and travel tabs for the first half of my pregnancy.
