Batman is in it to win it.

Ben Affleck has completed 30 days in rehab, but he plans on extending his stay to ensure the success of his recovery.

"He is doing much better but needs to continue receiving care. As difficult as it was to have his recent trip to rehab all play out so publicly, it now seems the way it happened was for the best. Ben seems to take this rehab visit more seriously. This time is different. He doesn’t want his kids to have to go through this again. Ben is really trying very hard to get better. He is taking things day by day, but it seems he plans on staying at the treatment center for at least a couple of more weeks," a source dished to People.

This time around, the Oscar winner has a very structured plan in place to make sure his sobriety sticks.

"He has a specialized program to suit his needs — meetings, working out, reading, therapy. Everyone’s journey with addiction and treatment is different and built for the individual. [Affleck’s] is a good mix of mental and physical work. This is what was outlined by his doctors and team," the source added.

We're rooting for him!
