@bushelbasket Thanx. That maybe won't be too bad. I just hope like heck that I get a good administrator of the tests and that if I say stop, they will respect my wishes. If not, I'll clobber them and then maybe they'll realize I'm not joking. I'm not above slapping the crap out of someone. Once, a nurse evidently didn't think my ankle was as touchy as I let on and I kicked the heck out of her teeth with my good leg and she never questioned my sincerity again. When I say stop, I don't mean for a teeny tiny break; I mean stop; I'm quitting and going home now. That is EXACTLY what I will stupulate in my agreement to having the procedure done and they better be sure that I MEAN every word of it! This may be a great diagnostic test, but I am not going to be tortured.
