Michael Madsen Ordered to Get Extra Help With Booze Problems

"Reservoir Dogs"
star Michael Madsen has completed his 30-day stint at an intensive alcohol treatment facility, TMZ has learned -- but sometimes enough is just not enough ... because a judge ordered him to undergo even MORE treatment for good measure.

TMZ broke the story ... a judge ordered Michael to check into the in-patient rehab program last month, following his 2012 DUI bust when he was popped driving on PCH with a blood alcohol level over TWICE the legal limit (allegedly).

Michael was in court Monday -- to prove he'd completed his mandated 30 days -- but the judge wasn't convinced 30 days was enough.

The judge was definitely pleased with Madsen's progress, but still wanted the actor to go the extra mile ... ordering Madsen to enroll in an outpatient program to help stay on the straight and narrow.

One day at a time.
