As residents, we were working as much as one hundred hours a week; though regulations officially capped our hours at eighty-eight, there was always more work to be done. My eyes watered, my head throbbed, I downed energy drinks at two A.M. At work, I could keep it together, but as soon as I walked out of the hospital, the exhaustion would hit me. I staggered through the parking lot, often napping in my car before driving the fifteen minutes home to bed.
