What is the sedation like for getting 4 molars extracted?

I just had my wisdom teeth removed, and the same anesthetic (the thing that makes you numb or sleepy) was used. Its pretty much another word for laughing gas. The needle goes in, your like "okay here goes".. you wait for the sleep part, and the next thing you know, your awake again like nothing happened. Be aware, after you come out of the sedation your going to be very dizzy, and everything WILL seem hilarious, but try not to laugh too much. after the laughing wears off, you'll be in some pain. make sure you get some pain medications.
