Lindsay Lohan says this time it’s going to be different.
Lohan said she’s in “a different head space” now and vowed to stay “present and clear-headed and focused.”
“I feel whole again,” she told Winfrey, “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.”
Lohan, 27, completed her latest court-ordered stay in rehab in July. She must continue therapy into late next year.
She acknowledged an addiction to alcohol, which “in the past was a gateway to other things for me,” but she offered no specifics other than cocaine, which she said she has used no more than 15 times.
Winfrey asked her what she’s on these days. Lohan replied, “Vitamins.”
