"Provigil" (I find that name hilarious), made by Cephalon Inc., is a drug that keeps you awake. From the New York Times:
...growing sales of Provigil are also raising questions about the company's promotion of the drug and about society's use of it. Already, some doctors say, Provigil is showing signs of becoming a lifestyle drug for a sleep-deprived 24/7 society, used by people who need to pull all-nighters for work or school or who just want to sleep less so they can work or play more.
