Lindsay Lohan: I'm Going Back On Adderall When I Leave Rehab!

Lindsay Lohan is telling close friends that once she is released from Betty Ford she plans on taking Adderall again, even though the starlet's rehab doctors took her off the medication, RadarOnline.com is exclusively reporting.

"She has been a bitch on wheels," the source said of Lilo since she stopped taking the Adderall.

"Lindsay is hell bent on getting a refill of her Adderall as soon she leaves Betty Ford. The medication she has been taking for her ADD isn't working, and she's constantly complaining about it. Lindsay doesn't care what the doctors at Betty Ford say about the dangers of Adderall.

The source went on to exclusively tell Radar, "She has no chance of staying sober if she starts taking the Adderall again because it's an amphetamine based drug. For an addict like Lindsay, it's a trigger for her to use other drugs."

As RadarOnline.com previously reported, Lindsay's Adderall was taken away from her last week by doctors at the Betty Ford Center and the troubled actress has gained five pounds and is complaining that she can’t stop eating.

Lilo revealed her Adderall use in a recent interview with Piers Morgan on the Daily Mail saying, “I have severe ADD (Attention Deficit Disorder). I can’t stand still. So I take Adderall (a prescription drug) for that, it calms me. I know people who take it to stay up, or girls who take it to supposedly stay slim because it kills your appetite. But I eat all the time. I just take it to stay calm. It works well for me."
