Although funnyman Robin Williams has been sober for several years, he’s checking into rehab for a little maintenance.
The actor, 62, plans to stay in the treatment facility for several weeks.
Williams quit cocaine and alcohol cold turkey in 1982 and stayed sober for 20 years.
The “Crazy Ones” actor then fell off the wagon and sought treatment in 2006.
Williams is dad to son Zachary, 31, daughter Zelda, 24, and son Cody, 22.
