Josh Brolin says he's done drinking alcohol for good ... after Friday night's cabbie-raging bouncer-fighting debauchery.
We posted both videos over the weekend -- one showing Josh fighting with a cab driver after he rear-ended the guy, and the other showing Josh drunkenly fighting a bouncer for trying to move him outside a bar.
Now it appears Josh has learned his lesson, telling a photog today that this kind of nonsense will never happen again.
He says he regrets the entire night, and will never drink another drop of alcohol as long as he lives. Big talk.
