morning sickness and craving

Does anyone else get craving but can't eat because you get stomachache and is vomiting it? But there is one food that you will eat all day and night and it's like nothing? Well I crave all this foods but I can't handle it and I don't feel well all day but if I eat soup it's like nothing. I crave it most of the  time (soup that is) but there are other food that I would like to eat as well.
