Had mine out with a local, no sedation. I just couldn't stand another bloody IV.
I've got a great breathing and counting technique that I use in those circumstances. Despite me telling the theatre staff not to talk to me, there was a constant parade of women popping their heads over the blue sheet getting in my face, telling me how well I was doing. Completely screwed up my numbers...
In the end I reverted to factory settings and snarled 'Will you all shut the fuck up'. Offended silence. Other than that, it wasn't too bad and I could drive myself home an hour later.
