John Stamos is getting candid about his recent rehab stay for substance abuse.

"I've had a rough year with my mom dying, so it all came to a head, and it was a turning point. You either continue on that path — and some of it's fun, but a lot of it's not — or there's this other thing, this golden opportunity sitting there with all this work and all this goodwill that you have going for you. That's the key," the 52-year-old actor said in a new interview with Details.

"I can't wait to get to work in the morning," John recently told Entertainment Weekly of his new projects. "I haven't felt this in a long time. I feel better than I've felt in a decade. And I hope people see that. That's what I want them to see."
