I'm apparently insensitive to propofol, so I got to have my procedure awake.

Whatever the pre-propofol drug was did mildly sedate me, so it wasn't so bad. And I was able to banter with the anesthesiology nurse and the gastroenterologist the whole time.

Good news! The preliminary lab report says the ridiculously large collection of polyps are tubular adenomas, which are benign growths.

 My being laid off from Harvard does not invalidate my retirement benefits.
