Big chicken here. I always opt for the sedation. And the sedation is one of the best drug cocktails ever. I'm just saddened that the leftovers can't go home in a doggy bag. But I'm pretty sure that I'd be able to do the procedure without sedation if I had to. So do whatever you'd be most comfortable with.
And I'm sure you've had the procedure by now so it's all moot (or mute as I heard a tv news anchor say.... )
