B6 for nausea

Samantha
I picked up some B6 to try to help with the nausea. I'm curious, if you take it when do you normally take it? Morning or evening? I take my prenatals before bed because they were making me sick. My doctor prescribed me Diclegis which you're supposed to take at night. I chose to try B6 before going to those Meds. 
Just wondering which would be most effective based off of what your doctors may have told you!
