|Lindsay Lohan tells all in Oprah interview|
The troubled actress, Lindsay Lohan
, completed 90 days of court-ordered treatment for substance abuse earlier this month and insists her latest stint in rehab has changed her life for the better.
In a highly publicized interview with Oprah Winfrey's
talk show 'Oprah's Next Chapter', which aired on US TV, she said: "I feel whole again and I have such a desire to want to keep this feeling and stay this way, and I'm willing to do whatever it takes."
The 27-year-old star further claimed she was in a "different head space" since her stay at the Cliffside Malibu treatment center in California, and has vowed to stay "present and clear-headed and focused" now that she is out of rehab.
Grilled about what she is taking these days, Lindsay asserted to Oprah she only takes "vitamins" and a prescribed drug called Nexium, which is used to treat acid reflux.
The 'Mean Girls' star candidly admitted a past addiction to alcohol, which she says "was a gateway to other things for me", and owned up to using cocaine around 15 times.
As well as the interview with Oprah - which was filmed just days after she left rehab - Lindsay will star in an eight-part reality series for the talk show host's OWN network next year.
