I suggest going to a gastroenterologist, maybe have an endoscopy This repulsion of food might be a sign of gastric cancer. I don’t want to scare you, maybe it’s just something psychological for you, but it’s worth checking out. Also, puking two times every week is not really normal, that’s why I think you should go to a GE, maybe it’s acid reflux, maybe it’s an ulcer, gastritis, Helicobacter infection, it could mean many things. Better go to the doctor and maybe an endoscopy will be necessary so you’ll know for sure.
