I'm so sorry... I can't imagine that kind of misery. I'm due on the 7th as well, and just this week I weaned myself off my nausea meds, so had I not taken them, I would have been in for the long term nausea. I took vitamin B6 with unisom, a fairly widely-used treatment, and it's an actual precription pill in Canada, I hear. It was low-risk, cheap, and a cure for me.. worth a try. Hope you can catch a break before the baby comes!
I"m off to the store today when I feel a little better to try the unisom....I SOOOOOOOOOO hope it helps. THe seabands did NOTHING =(
