I never threw up with either of my girls (sorry, not bragging) however i did have the all day queasiness with them, especially #2. Whole foods had an all natural morning sickness tablet, I want to call it "good Mornings" or something, anyways, you take it before bed and I think whenver else u need it, but it really seemed to help the nausea. Also, they carry ginger chews and ginger pops and those are what i lived on, never left home without them. I probably would have been praying to the porcelain god when prego with number 2 if I didnt have these things, good luck!
ps. also, mint tea is always great, prego or not!
