Sometime in the 1990s, the concept of better living through chemistry turned a corner, thanks to drug companies’ efforts to synthesize antidotes for every possible mood swing. So writes Yale lecturer Charles Barber in his new book, Comfortably Numb: How Psychiatry Is Medicating a Nation. An OCD sufferer himself, Barber spent a decade working in places like New York City’s Bellevue Hospital. He knew something was wrong when he discovered that his colleagues’ perfectly functional, $300-an-hour Upper West Side clients were taking the same potent pills as his own schizoid, homeless, crackhead patients. “I would spend part of the day in shelters dealing with seriously ill people,” Barber says. “Then I’d go to cocktail parties and find out that the people there were on the same medications.” He proposes that we just say no to multinational drug peddlers and heal ourselves with cognitive and dialectical behavioral therapies — “talk therapy” techniques that minimize pill pushing, dispense with Freudian dream analysis, and engage patients in actively reprogramming their own brains. It’s like “a highly selective carpentry of the soul,” Barber writes — therapy as self-engineering.
