I take a complex vita B vitamin. It is a whole food vitamin though, so it's not measured the same as the synthetic. I was actually vita B deficient after both of my previous pregnancies (which caused me to have dizziness and migraines)... so it might be worth your time to take that supplement!
I got a "stuff to know when you're newly pregnant" packet from my RE and she said up to 200mg of B6 (divided into 3 doses) daily, in combination with Unisom in the evenings, is recommended for nausea.

Re: anyone take extra b6?
