I fell asleep five separate times during my shift. Each time, when the system saw that I’d drifted off, it sounded a warning klaxon in my ears, jolting me back awake. Then it noted the infraction in my employee data file. My narcolepsy had become such a consistent problem during my first week that I was now being issued two little red pills each day to help me stay awake. I took them too. But not until after I got off work.
