I got mine done three years back at 36 (I've had gastric issues, and my mom has colorectal cancer) - didn't use sedatives or anesthesia. Pain tolerance is relative, so my own experience wouldn't carry over.
I can understand if some people want sedatives, but anesthesia is pretty high risk like you were saying.
Its not my responsibility to look for evidence if you're making the claim.
If you want to come into a thread telling people that are already apprehensive about a procedure "please don't do X its dangerous!" when an _actual_ first google will give you a Mayo Clinic saying its perfectly fine, then you need to provide some fucking evidence.
Your evidence is unconvincing, but good job being condescending.
