Hey congratulations! I went through 2 pregnancies without vomiting, and the second one I was nauseous as hell, but still didn't get sick.

Whatever you do don't NOT EAT (so in other words...EAT!) An empty stomach is terrible for morning sickness. In fact, people recommend you keep crackers by the bed and eat a few before you even get up. I used to carry graham wafers around with me all the time.
