As soon as she gets out of rehab, LINDSAY LOHAN tells pals she’ll resume her daily dose of speedy diet drug Adderall.

 Even though the starlet’s rehab doctors took her off the medication, Lohan is telling close friends that once she is released from Betty Ford she plans on taking Adderall again, reported.

“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 also said, “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.”
