The smaller we are, the easier we can morning sickness?

Is it true that if we are petite size, we tend to suffer from morning sickness longer, as compared to people who are of average size? I am 1.52m, less than 50kg. I am not skinny, just someone who is very small frame. My morning sickness is so bad that I threw up whatever I eat, hunger bang makes me vomit more. What’s your height and weight before pregnancy? Is this source reliable?
