Yeah twice
Once not sedated because I drove there alone and didn't want to wait all afternoon before I could drive again
Once with sedation but needed someone to accompany me / drive
Without sedation, I gagged continuously, and it didn't felt very good. I swore I would never choose that option again. It shouldn't even be an option! Horrible experience
With semi-sedation, it's a breeze. Nobody should complain, and if they do, they should be made to choose non-sedation next time!
