i had to get an upper G.I. this morning. strip to my undies and lay on a table while drinking chalky barium. then they take all kinds of xrays of my belly. it was a trip to watch the live screen of my stomach processing the barium. i felt a little like gumby when they moved me into different poses, shaping my legs and arms. my doc thinks i might have a hiatal hernia between my stomach and esophagus, due to my heartburn every single night. good times.
