I was the same with my third pregnancy....my first two I was nauseous or would only throw up once in the morning but my 3rd was bad, had to take zofran the whole first trimester....I'm preggo with my 4th now and unfortunately the "morning sickness" was even worse...immediately 28 weeks now, I lost 7lbs before the zofran in the first trimester and sadly am still taking it once a day or I spend all day sick.
