I probably should have had one already, having recently turned 54. Was going to do it, then COVID happened. I guess I should think about scheduling it. I have just heard horror stories about the prep. I had one friend who did the prep. She showed up for the Colonoscopy, and the power was out in the facility that day. She had to reschedule.
These days, many people are doing Colonoscopy and Endoscopy at the same time. I had one friend who had both at the same time. I told him to make sure they did the Endoscopy first. Because, if they did the Colonoscopy first, it might leave a shitty taste in his mouth.
