Stephen Colbert Shares His Struggle With Anxiety and Why He Stopped Taking Xanax | Entertainment Tonight"I was actually medicated," he says. "I mean, in the most common, prosaic way. Xanax was just lovely. Y’know, for a while. And then I realized that the gears were still smoking. I just couldn’t hear them anymore. But I could feel them, I could feel the gearbox heating up and smoke pouring out of me, but I was no longer walking around a couch." "I had a bit of a nervous breakdown after I got married -- kind of panic attacks," he continues. "My wife would go off to work and she’d come home -- because I worked at night -- and I’d be walking around the couch. And she’s like, 'How was your day?' And I’d say, 'You’re looking at it.' Just tight circles around the couch."
