NEW YORK (AP) – Lindsay Lohan says this time it will be different – really. She tells Oprah Wifnrey her sixth try at rehab is working out. Lohan describes herself as being in “a different head space” now and promises to stay “present and clear-headed and focused.” Lohan is 27 and has been in and out of rehab in recent years. She ended her most recent court-ordered stay in rehab in July – and must continue therapy into late next year. She says the only prescription drugs she’s on these days is Nexium – for acid reflux.
