How bad is it to have your wisdom teeth removed????

I really need some reurance about this! I am soooooooooo freaked out about being put to sleep through IV anesthesia! I am also scared of how i will feel afterwards! I have two bony impactions, and the other two are all the way through, so they just have to be extracted! Please, I would love to hear from someone who has theirs out! Please nothing scary, don't need to make it worse! Thanks!
