The former 'Friends' star said in a statement that he's once again seeking treatment, his third stint since 1997. 'I'm making plans to go away for a month to focus on my sobriety and to continue my life in recovery,' he said. 'Please enjoy making fun of me on the World Wide Web.' The 41-year-old has struggled with addiction to prescription pills and alcohol in the past, but hasn't suffered a relapse, sources told People.com. He was last in rehab in 2001, but this time the trip is a proactive measure to fight his addiction, TMZ.com reported.
