Not exactly same, but my epidural wore off while they were shoving my guts back in during c-section. I do not recommend this to anyone.

None of these choices fit my answer. I have heard about it but it has not happened to me.

I am a redhead, and as such have a different metabolism and response to medications than do other people. I was at the beginning of a neck surgery when the surgeon asked me to stop crying, as I was moving (he said it nicely, but still.) I told him I could not help myself, as what he was doing HURT! He was amazed, and gave me more anesthetic. That has happened to me many times - most notably during dental procedures. I require half again to double a normal dose to achieve the same numbing properties as my darker-haired sisters and brothers!!

I voted for happened to me once but it has happened 2 times.

i've had a few of them & don't think i was completely out for any of them. pretty sure they just gave me a valium drip & i watched the screen. in only 1 did i feel a sharp jab of pain.

I woke up while having my tonsils removed as a 5 year old.
I specifically asked to stay awake during my colonoscopy a few years ago, thinking it would be fascinating, but fell asleep from boredom. No pain at all.....

A nurse I worked with woke up during her cesarean. She remembers what the doctors were saying, then they realized she was awake and put her back under.

I have a memory from when I was four and had my tonsils out. Back then in the hospital and they used either. I awoke, just before the either, strapped in a bed, people in masks around me, terrified. The doctor said, we are going to count backward from a hundred. I panicked as I thought, I can only count to ten.

Need one more listing: never to me. I never had it happen, don't know anyone, but, definitely have heard about it happening. Sounds awful. I have even heard of people who are conscious, in pain, and unable to communicate.

I don't think they put you to sleep. They give you a roofie to forget . I don't think you stay under at all.
