Sickness

I'm 4 weeks post-op. I was in the hospital last week because of pancreatitis, I was eating fine for 2 days then I started throwing up after anything I eat, even apple sauce. I tried to go back to liquids and that still makes me sick. Any who has has this problem with vomiting after eating, if you've taken the nausea medicine has it helped, I'm not nauseas but I didn't know if it helped with the food. I go and see my doctor Wednesday
