Something to look forward to: I still have a text from my imaging people responding to my question "If I run a half marathon four days before the PET will it hurt anything?" He's a good friend and his paraphrased response was "I'm not sure. We don't PET many elite level athletes." I'm not elite but his saying that sure made me walk a little taller for a while. This path isn't easy but it's doable. Keep a fighters attitude and you'll be on the other side of this in no time !
