In solidarity, Dr. Oz and Dr. Grayson do it too. "It's vitally important to support Brian and show him I can do this too and not die," Dr. Oz says.
At the moment of truth, Brian confronts his fear and sits on the toilet seat. "I hated it. I've lost a lot of things from OCD. I've lost a marriage, a nice house, a couple good jobs," he says. "Just to get back the ability to be able to go into the bathroom is a big step for me."
Dr. Grayson says while his treatment for Brian may look akin to torture, it really isn't. He also emphasizes that he did not force Brian to do something he didn't want to do. "The art of therapy is talking them into it and helping convince them and support them. Convincing them they're ready to be terrified," he says. "Partially, it's reminding them ... what their life has been like. In the moment of confronting fear, the fear becomes overriding, and you forget all that you've lost. You also forget that the worst thing about [obsessive-compulsive rituals] is they don't work. It doesn't protect you from germs."
