I was talking to my doc about my second one telling him I was looking forward to that hit of versed to knock me out. He told me they stopped using it, switched over to propofol or however you say it - what killed Michael Jackson. He said its a lighter sleep and you come out of it faster with less hangover.
He was right, I woke up and no grogginess.
My first colonoscopy, I woke up when he said he found a polyp and I could feel him trying to get it but it was like a moment of clarity, then I went back to sleep
