Serious but funny stuff! When I had mine last year, everything went fine until the nurse said I couldn't drive for 24 hours (legally, because of the sedative). I had a shoot at the nearby Toyota plant that evening, so I told the lady that I would have to cancel. She told me that 20-30% of the population do it without any "help".
That's what I did, and I can tell you that the hard right turn into the intestine is a "mother"******.
After the proceedure, the Dr. said in his 20 plus years, he had only done a few without sedatives. When I told him what the nurse said, he laughed and said that some try, but that's why they leave the needle in your hand.
Watching the proceedure totally coherent as shot by a miniature camera is a trip...looks like the grand canyon.
Anyway, not a great experience, but, given schedule conflicts, I'd do it that way again. I was back at work on a film score within 45 minutes.
We ALL need to make sure we do this life-saving proceedure when it needs to be done.
Hey, you hold-outs; don't be a "pain in the ***!".
