For about three weeks now, I have been unable to keep any meal involving solids down. Within 10 minutes of eating breakfast, lunch and dinner (especially dinner), I vomit. Right before I vomit, I begin to feel mucus building up. This does not happen when I do a protein shake or juice. It only happens when I eat solids, including chicken, pork chop, steak, spinach, asparagus, rice, sandwich, etc. This happens even if if I eat a very small portion. I am also extremely fatigued after the episode of eating and vomiting. Help!
