I missed mine last year and still haven't scheduled it for this year I am one bad girl. You know how a prescription blank has the place where the doctor signs to substitute or not so you can get a generic? When my doc wrote out my script for my boob vice, he signed on the may substitute line. So I'm still trying to decide what to substitute it with. Maybe my husbands testicles? Or maybe the doctors or the person who invented the boob vicegrip.
