I started taking 50-60 mcg Vitamin B6 daily (half in the morning, half at night) eight days ago. I also started wearing accupressure anti-nausea bands six days ago. I don't know if I'm experiencing a placebo effect, but here at the end of my eighth week of pregnancy, I have yet to throw up. That's very unusual for me.
Sure, I still have morning sickness. I'm tired much of the time, and my odor sniffing abilities rival those of Gus on Psyche. But I'm not hanging over the toilet. :) Maybe I'm having a boy and so the hormones aren't as strong this time around. Or maybe Vitamin B6 and the wristbands really are helping me. If they are just placebos, I don't want to know because then the placebo effect might go away!
