Unisom/B6

My Dr recommended Unisom and b6 for morning sickness. I've been taking 50 MG of b6 at night with 25 MG of unisom. Works great at night (when I'm at my worst) and mornings have been better. I noticed it starts to wear off and I feel crummy from like...2 on til evening.

I guess I'm wondering if anyone else is taking this combo and how much/when is working for you? I have an appointment Wednesday so I just have to make it that far...but have to survive through a long car ride and wedding tomorrow...
