What's been up with Tony?

If you are a Tony fan (like me), you have to be wondering what has been going on with Tony Stewart this season. Part of his appeal is his cocky, arrogant attitude. Tony lays it all out there. He sometimes shares too much.

I was all for him leaving Joe Gibbs Racing and branching out on his own. I have watched in awe as he finagled his way through this season with such success (and in the chase). What is somewhat disturbing to me is his calm demeanor.

I just have to ask. Is Tony Stewart on Paxil or some other mood-altering drug?
