At first it seemed like a few random cases of lassitude among Mary Chapin Carpenter devotees in Berkeley, Cambridge and Chapel Hill. But then psychotherapists began to realize patients across the country were complaining of the same distress. They were experiencing the first hints of what's bound to be a national phenomenon: Obama Comedown Syndrome.

The afflicted had already been through the phases of Obama-mania -- fainting at rallies, weeping over their touch screens while watching Obama videos, spending hours making folk crafts featuring Michelle Obama's face. These patients had experienced intense surges of hope-amine, the brain chemical that fuels euphoric sensations of historic change and personal salvation.

But they found that as the weeks went on, they needed more and purer hope-injections just to preserve the rush. They wound up craving more hope than even the Hope Pope could provide, and they began experiencing brooding moments of suboptimal hopefulness. Anxious posts began to appear on the Yes We Can! Facebook pages. A sense of ennui began to creep through the nation's Ian McEwan-centered book clubs.

Up until now The Chosen One's speeches had seemed to them less like stretches of words and more like soul sensations that transcended time and space. But those in the grips of Obama Comedown Syndrome began to wonder if His stuff actually made sense. For example, His Hopeness tells rallies that we are the change we have been waiting for, but if we are the change we have been waiting for then why have we been waiting since we've been here all along?
