What is laughing gas like?

Tomorrow, I am getting a procedure done where they are pulling out my last baby tooth that refuses to come out and then connecting a chain up to the adult canine tooth and pulling it down throughout 6 weeks. They are giving me a huge dose of pain meds to take an hour before I go in. Then they are giving me laughing gas. He's just super insane, but really nice, and I am not scared or anything. Except for the laughing gas, and I think that's pretty funny because you're supposed to feel relaxed and fine. I guess I am really nervous about what I will say. I don't have any huge secrets, but things I rather not have my oral surgeon hear nor my mother. I know I might be a little unstable after the surgery, but I was just wondering a couple of questions.

1. Will you talk on laughing gas?

2. Do you go to sleep or stay awake?

3. Do you feel anything?

4. How long does it last after the surgery?

5. Do you do anything...crazy?

Thanks so much!
