Ben Affleck completed treatment and left his Malibu rehab on Wednesday morning, X17online can report exclusively.

The actor, who was taken to the facility on August 23 by Jennifer Garner following an intervention, stayed just over 30 days while working on his sobriety.

A limo arrived at his bachelor pad today, after he was escorted to his Pacific Palisades home, to take him to Warner Bros. for something work-related, and he spent several hours there.

It's not like it's back to business as usual, though!

A source tells X17:
    "He will still have a counselor closely monitoring him, and he will still be attending meetings and therapy. The only thing that's changing from being in rehab is that he's now allowed to sleep at home. He's basically skipping the transition to a sober living house and will just get the necessary treatment while living at home. It's important for him to be near his kids."
