I had a scope last year and after leaving the hospital, I had the most painful cramps ever from all the air that they blow into you for the scope. I was doubled over in pain, not wanting to pass any gas as I had some biopsies done as well and didn't want to pass any blood. My best friend got me to a Zeller's store which has a huge bathroom. I sat down and I passed air for I swear a whole minute and it was LOUD. The bathroom was, of course, full. I was laughing quietly to myself and then couldn't resist saying out loud "Whoa! I don't remember eating THAT!". I agree that you have to have a sense of humour
