I will say that it sucks being sick anytime with a stomach ailment, but during pregnancy, I was able to get over it faster. My doctor had prescribed the anti-nausea medication, Zofran. I phoned the doctor and she told me to change the dosage and to eat yogurt. I didn't want to eat. "Um, my stomach is not agreeing with any food."

Surprise! It worked. Within 8 hours I was able to eat and no more ailment. I was tired and weak for a few more days, but it stopped the initial problems.
Best of luck it stops soon. And give that helper a big hug.
