Robin Williams, who has had an ongoing struggle with substance abuse, has reportedly checked himself into a rehab facility to avoid falling off the wagon.

Robin Williams Back In Rehab

Williams is currently in rehab at the Hazelden Addiction Treatment Center near Lindstrom, Minn., reported TMZ. He’s reportedly receiving treatment to maintain long-term sobriety at the section of the center called The Lodge.

Williams will remain at Hazelden for several weeks.

"After working back-to-back projects, Robin is simply taking the opportunity to fine-tune and focus on his continued commitment, of which he remains extremely proud,” the actor’s rep told TMZ.

Williams, who had a proclivity for cocaine and booze in the 80s, eventually quit everything cold turkey. In 2005, Williams fell off the wagon and went to rehab.

In 2014, Williams will be seen on the big screen in Boulevard, The Angriest Man in Brooklyn and Merry Friggin' Christmas. He'll be reprising his role as Teddy Roosevelt in Night as the Museum: Secret of the Tomb for 2015 and is rumored to be reprising his titular role in Mrs. Doubtfire 2.
