On the morning of the stroke, I woke up to a pounding pain behind my left eye. And it was the kind of pain -- caustic pain -- that you get when you bite into ice cream. And it just gripped me -- and then it released me. And then it just gripped me -- and then it released me. And it was very unusual for me to ever experience any kind of pain, so I thought, "OK, I'll just start my normal routine."
