I'm wondering if anyone knows or knows of someone with this problem. My son is 25 and has been vomiting most mornings for the last 5 months. He has had various blood work, all good, ct scan and mri of his head, all was good, as well as endoscopy and biopsies done of his stomach. His bowels are fine. His specialist is at a loss to figure out what is going on. He has prescribed Zofran and an antacid, but these don't seem to be helping much. He has lost a lot of weight. By noon the vomiting has stopped and he is left feeling tired and frustrated. Any ideas?
