He failed miserably at getting Lindsay Lohan to enter rehab -- but Michael Lohan was one of the main reasons Octomom is now getting help for drug abuse ... because he helped arrange her treatment program ... TMZ reports.
Michael tell TMZ, he's been running a nonprofit organization based in Florida for the last nine months that stages interventions for people in need of substance abuse treatment ... and so far, he's already performed over 25.
Sources close to Michael say, Octomom's manager, Gina Rodriguez recently voiced her concerns to him about the mother of 14 issues with dependency -- so Michael and Gina decided to take action last week, making arrangements for Octomom's treatment program.
Michael said, "The most important thing is the willingness to realize and surrender to the issue and commit to getting help, which Nadya did!"
He adds, "If it wasn’t for her manager Gina, my good friend, Tim Chapman at the Chapman house/Teen savers and Gina's daughter, this would not have been possible. They deserve a lot of credit!"
Octo's currently in a 30-day in-patient program for Xanax abuse, but she still gets to call her kids twice a day.
