Dude, he was over in Russia the whole time getting some sort of experimental treatment for addiction... No Joke.

I don't know what they do in Russia, but I've read of these new what they call "vaccines" for addiction where you get the shot and it actually eats away at a part of the brain responsible for impulsiveness and they've apparently had some good results with that. But while it might make you stop wanting to follow through on your addictions, it also changes your personality in other ways.
