The caffeine trap

Here's an excerpt of a National Geographic article about caffeine.

A neurologist interviewed for the article describes what could be called "the caffeine trap":

"The principal reason that caffeine is used around the world is to promote wakefulness," [Harvard Medical School neurologist Charles] Czeisler says. "But the principal reason that people need that crutch is inadequate sleep. Think about that: We use caffeine to make up for a sleep deficit that is largely the result of using caffeine."
