Lohan was arrested twice last year on DUI charges and pleaded guilty in August to misdemeanor drunken driving and cocaine charges. She served 84 minutes in jail as part of a plea deal, and checked into a rehab center in Utah.
"I've learned so much, though, like learning to live my life a different way ... and I wasn't taking the time to feel my feelings," she says. "Being away and going to a place where I could learn about that and take the time with a clear mind to get back on the right track was nice."
The "Mean Girls" star - who was shown on a video taking a swig from a champagne bottle while ringing in the New Year in Capri, Italy - says it's hard to resist the urge to party.
"I have it in me to go, go, go," Lohan says. "I'm still young. I love life. I love music and being around that. I love people, and I'm a very social person. But I also love being home, quiet and normal."
