Pat O’Brien, co-host of The Insider, has returned to a rehab center.
The entertainment host “has entered a rehabilitation facility for treatment,” according to a statement posted on the Insider’s Web site. “O’Brien and his doctors felt this is the best course for maintaining his sobriety.”
O’Brien, a veteran of CBS Sports and Access Hollywood, first entered a rehab program in 2005. In a statement at the time, he said, “I have had a problem with alcohol. Overcoming this problem is a top priority in my life.”
After completing a 40-day program, O’Brien told PEOPLE, “When you hit the bottom with this disease, it’s a real bottom, like being in a grave that hasn’t been covered yet.”
He said that his break from drinking had allowed him to see that “on the other side of that door is hell. And I’m not ready to see that again.”
