  • The hours: "I work from 6:45 p.m. to 6:45 a.m. testing super-absorber polymer, which is the material used to line diapers."
  • Why I took the job: "I'm nocturnal — been that way since I was little. I really like the lifestyle. Shopping during the day is much easier and faster."
  • The trade-off: "I've fallen asleep at the wheel very briefly a couple of times while driving home. Luckily, nothing bad happened. Once I fell asleep on the toilet and almost fell in."
  • How I stay motivated: "I play my iPod and dance around the lab when no one's looking. When I'm off, I love wearing my Christian Louboutin heels and Badgley Mischka dresses."
  • Secrets of an overnighter: "Diet Cherry Dr Pepper. I probably go through at least four cans a night."
