Yep ... I used to accompany my mother when she had to have hers ... three times.   She was always amazed it had already been done when she came out afterwards.   She didn't remember a thing.   But then she was accustomed to doctors seeing every inch of her body, prodding, pulling, pushing, injecting, etc etc.   As for me, I'm not.  They'll have to drag me in kicking and screaming!
