Eating nausea

So I have what my doctor calls "Eating nausea" meaning that I have no appetite most of the time but when I DONT eat I get sick, and if its not exactly what I am craving it doesnt help at all and I still get sick. It started literally around 4 weeks and is still going strong at 8w1d......anyone else have this and if so do you have any recommendations for it?????? I only had typical morning sickness with my son so this is pretty new to me!
