" here had been times when I’d wandered around in a daze for as long as two weeks after a shock treatment, living in that foggy, jumbled blur which is a whole lot like the ragged edge of sleep, that gray zone between light and dark, or between sleeping and waking or living and dying, where you know you’re not unconscious any more but don’t know yet what day it is or who you are or what’s the use of coming back at all—for two weeks. If you don’t have a reason to wake up you can loaf around in that gray zone for a long, fuzzy time, or if you want to bad enough I found you can come fighting right out of it. This time I came fighting out of it in less than a day, less time than ever. "
