Brolin's reported decision comes a few weeks he was videotaped in a drunken brawl with a bouncer at a Santa Monica, Calif., bar on Nov. 2. Over the same weekend, the actor was also caught on tape getting into verbal altercation with a cab driver who rear-ended him at a Del Taco drive-thru.
Two days later, Brolin told TMZ he was "completely done" with drinking and he "absolutely" regretted the incidents.
Earlier this year, Brolin was arrested on New Year's Day for public intoxication and spent six hours in jail. The following month, he split from Diane Lane after six years of marriage.
An email to Brolin's rep was not immediately returned.
