John Stamos is looking to clean up his act.
The actor has checked into a residential treatment facility to seek help for substance abuse, a source confirmed Friday to E! News.
No further details were immediately available but the move comes just shy of a month after he was arrested for an alleged DUI in Beverly Hills. At the time, he wasn't taken to the police station but to a hospital for observation for what appeared to authorities to be a possible medical condition.
"Thanks to everyone for their love & support," the star of Fox's upcoming sitcom Grandfathered tweeted the next day. "I'm home & well. Very appreciative of the BHPD & Cedars for their care."
