I glanced up at the digital display and watched the next full minute turn over. Another four hours for Miller. In the routine the Hendrix was running, he would not get hungry or thirsty, or have to attend to any other bodily functions. Sleep was possible, although the machine would not allow it to become a withdrawal coma. All Miller had to contend with, apart from the discomfort of his surroundings, was himself. In the end it was that which would drive him insane.
