I had it done when I was in high school. They gave me a single dose of valium to take the morning of the surgery, I guess to keep me calm and relaxed. It helped, as I don't really remember feeling nervous about it at all. My doctor looked and sounded like squidward.
They put an IV in my hand and several moments later they told me to count back from 10. I probably didn't make it past 8 before it felt like I was melting into my chair, and falling backwards away from my own field of vision. Then I woke up, without having perceived the passage of any time. I felt extremely intoxicated and the first thing I did was put a dopey grin on my face and flirt with the nurse who was in the room with me. I said something like "Heey.... how u doin?

They helped me stumble into some kind of chill-out room with a bed in it, where I collected myself for 5-10 minutes, then my parents came and took me home. They gave me some gauze to put on it to soak up any bleeding. The rest of the day there was some pretty moderate soreness, but nothing after that. They gave me a small bottle of vicodin which I didn't take. I ended up trying to use it recreationally a few months later but I didn't feel anything.
Overall I found it to be an enjoyable experience. Getting put under was interesting. Pain was minimal. Would do again
