When I abandoned the smoking habit of more than three decades I was given a supposedly helpful pill called Wellbutrin. But as soon as I discovered that this was the brand name for an antidepressant, I tossed the bottle away. There may be successful methods for overcoming the blues but for me they cannot include a capsule that says: 'Fool yourself into happiness, while pretending not to do so.'
