Diclegis and appetite?

I was prescribed Diclegis for nausea since I've been constantly throwing up and not able to eat. I feel a lot better after taking this medication but I'm still nauseous. I feel like it never goes away! I also have lost my appetite completely. Yesterday I was able to eat half of my lunch and that was it. I don't even feel hungry at all since I'm so sick. What should I do? I know I need to eat! Is there any foods you would recommend? I'm 9 weeks and hoping this goes away soon!
