"[He] is currently in rehab," his manager, Mark Burg, tells PEOPLE. "He was bombarded by every rehab in the country looking for his wallet and publicity, and he has been deciding where to go. With the help of friends and family, he finally agreed to go and went into rehab on Saturday."
While the location remains unknown, Sheen's game plan is not: Get – and stay – sober.
"Charlie knows he has work to do and he is looking forward to regaining his sobriety," says Burg, who is an executive producer on Two and a Half Men, Sheen's hit show that is on hiatus while the star focuses on getting healthy. "Charlie hopes to be back at work in the near future but there is no time frame. Regaining his sobriety is what is most important."
As for reports that Sheen flirted with checking into Promises, the Malibu-based rehab center he spent time at last year, Burg says it's not so. "Charlie never drove to Malibu," he says, "and Promises was not an option."
