REHAB: Lindsay Lohan Weight Gain Due To Drug Withdrawal: Adderall Usage Stopped For Recovery Purposes

Lindsay Lohan has reportedly been gaining a lot of weight while in rehab at the Betty Ford Clinic after Adderall was taken away from the actress.

According to RadarOnline, the 26-year-old starlet gained 5 pounds and has been going through withdrawal, "extremely emotional this past week and is finding comfort in food. Lindsay can't stop eating, and has gained five pounds because she has such poor eating habits. She has been exercising, but she just doesn't have a lot of energy because she is no longer taking Adderall, which is a psychostimulant medication that contains amphetamine. She has been talking to a nutritionist at Betty Ford about eating healthier," one source says.

Lohan admitted that she suffers with ADD and uses Adderall in an interview with Piers Morgan, "I have severe ADD (Attention Deficit Disorder). I can't stand still. So I take Adderall (aprescription 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."

According to a source at the clinic says the being tasty could also be the reason she's been gaining weight, "is the food at Betty Ford is really, really good. Meals are elaborate affairs, featuring lots of delicious desserts. Lindsay just can't say no to the food. She is complaining that the new medications doctors prescribed, which isn't amphetamine based, aren't working. She is just making herself miserable."

Will Lohan keep adding the pounds on for the rest of her stay?
