Brain Boosters

Two days from now I’m planning to further tweak my mind by taking a brain-boost pill. Called Provigil, it differs from its predecessors in that it is believed to home in on a section of the brain that helps govern alertness and memory. The pill is manufactured by ­Cephalon of Frazer, PA, and its active ingredient is called modafinil. The drug’s targeted delivery is supposed to prevent the side effects of stimulants that diffuse throughout the brain and rev up everything.
