Actor Charlie Sheen checked himself back into a drug rehabilitation center to overcome his "destructive appetites."

"I get bored easily and I'm bored with what I've been doing and it's time for a change," Sheen, 32, said in a statement read by publicist Jeff Ballard after the "Platoon" and "Wall Street" star decided Sunday to spend a month at the Promises rehabilitation center in Malibu."I'm looking forward to embracing life again," the statement said.

Sheen, the son of actor Martin Sheen and brother of actor Emilio Estevez, was discharged on Friday from Los Robles Regional Medical Center, where he was being treated for a drug overdose he had last week.

Sheen then checked into an unspecified drug rehabilitation center but walked out about 1:30 a.m. Saturday, Los Angeles County deputy sheriff Bob Killeen said. A doctor alerted authorities that Sheen needed supervision because he was taking prescription medication, Killeen said.
