Propofol
"Just got out of procedure for upper endoscopy and colonoscopy. Was very nervous about the anesthesia, which I'd never had before, but it was totally fine. No arm burning like some people have mentioned. I was out in 5 seconds, next thing I knew was waking up in recovery with my husband next to me. Though I felt mentally alert fairly quickly, it did take me a little while to feel steady on my feet. But all in all, I feel great and would not dread this procedure again. So to anyone putting it off: get over it, it's a piece of cake. Even the prep wasn't as awful as people make it out to be. Think about what people had to endure in the "old" days, like 100 years ago...this procedure could save your life and it really is no biggie."
