Not had that done personally, but the girl I live with had recently. The dentist said not to take any heed of any horror stories you might hear before hand, its rare enough, but people only hear about the bad cases. She had heard good and bad stories, but was fairly relaxed overall, and it went grand. When she came home after you'd hardly tell she had surgery at all, and she was surprised how easy it was. Some people do feel a bit drained after, and hence you might be advised to take a week off. She had a week off but said she could've gone back earlier.
Its very routine now, you'll be fine!
