It was at Iowa that I was diagnosed with hemifacial spasm disorder. My tic, which I attributed to caffeine, grew worse, enough so that I believed people noticed, though no one said anything. I remember rising up early in the morning for my CAT scan appointment. I lay on the motorized gurney that slid into the machine. The interior was smooth, white, and cylindrical. I felt like I was inside a gigantic hollowed-out dildo. I am the body electric, I thought, and my brain is going haywire.
