He agreed to go to the center in January after a TV interview with Dr. Phil McGraw but left after two weeks. Williams said at the time that entering rehab was a "rushed decision" and that he wanted to pursue job offers.
He now says he hopes to get "real recovery" and some rest. He says he wants to be able to say, "'Hey Dr. Phil. I did it."
Williams found fame after The Columbus Dispatch newspaper posted a web video of him.
