Colonoscopy is easy, it’s endoscopy that felt like near dear experience (I didn’t take the sedative= fail). Worth it though. Also the Dr’s and techs were far to busy talking about the next hairpin bend like they were rally driving. The satnav on the screen shows how far the scope has gone, I shit you not it really looks like the old Nokia snake gane. And when you have nitrous gas it all becomes very funny.
