I had the classic experience - eating the radioactive eggs and getting several images taken (for me it was after 30min, 1hr, 2hr, 3hr, 4hr). It was really simple - just eat the eggs and wait between scans. Honestly the hardest parts for me were that eating made me feel awful (such is life with gastroparesis right?) and it was exhausting. But other than that it was not too bad. Be prepared though - the eggs are rather gross haha. I hope it goes smoothly and that you get on track to some symptom relief!
