I would definitely opt for the conscious sedation if you think you'll be anxious. I have used it for dental procedures (crowns, root canals), and it is the bomb! I basically slept right through the procedures -- or that is how it seemed b/c I remember nothing.

You have to have someone there who will drive you home or they will not perform it, though. I'm not sure if just saying you have a ride who will come pick you up is good enough; I think they want to see and talk to the person ahead of time to make sure they understand their "duties", so it may have to be the same person who takes you to and from.

Good luck!
