I had just happened to read that a high percentage of Europeans do it without sedation, which is where I got the idea. Anesthesia is something I avoid as much as I possibly can. I wish now that I’d pushed more to get the endoscopy I had recently done without being completely knocked out, although the doctor (a different doctor) seemed a lot more resistant to that.
Endoscopy without anything but the throat spray was fine, the dry heaving isn’t awesome but unlike the endoscopy not eating the day before is no real challenge.
