Golfer Tiger Woods is being treated for sex addiction at a clinic in Mississippi. The report said Woods is at Pine Grove Behavioral Health & Addiction Services in Hattiesburg, Miss., according to Benoit Denizet-Lewis, a recovering sex addict, who has a source with knowledge of the golfer's treatment. Officials at the clinic would not confirm Woods' arrival, the report said.

Benoit Denizet-Lewis, a recovering sex addict, said a source with knowledge of the golfer's treatment has confirmed Woods is at Pine Grove Behavioral Health & Addiction Services in Hattiesburg, Miss.

Among Woods' first lessons, Denizet-Lewis said, will be that the oft-questioned addiction to sex is very real.

"We mock or it we say it's not a real addiction," said the journalist, who regularly contributes to the New York Times magazine. "But it's very much the real deal."

The world's No. 1 golfer will not have an easy time of it as he tries to conquer the demons that led him to repeatedly cheat on his stunning wife with multiple women, Denizet-Lewis said. "He's not going to be allowed to go out and golf in the morning," said Denizet-Lewis, author of "America Anonymous: Eight Addicts in Search of a Life," and his new book, "American Voyeur."

"He'll do like everyone else - get up early, eat the same food and go through the same emotions. ... It's a really intense experience," he said.
