I am experiencing something very similar to this scenario. My boyfriend is addicted to Adderall. It is prescribed to him. He does not have good health care so he won't talk to his doctors about getting off of the Adderall. He tries to go cold turkey and has mood swings, eats sugary foods for the up and sleeps all day everyday. Then when he decides he's had enough, he will start taking it again. His emotions are all over the map. I want to help but don't know what to do. I don't think that "we" can necessarily call their doctors as they are not allowed to discuss patient information with anyone. I have been reading about the withdrawl effects and it's pretty scary. I almost feel like I need to have an intervention or something. The best way to get off it is to ween off of it slowly. 30mg for a week, 25 for a week and so on. I know there is a definite psychological component that needs to be addressed. One thing I might do is research Adderall, its effects, side effects and withdrawl symptoms to help your friend understand that even though it is a prescribed drug, it is still a very dangerous drug. It is a methamphetamine. It's chemical composition is not that far off from street meth. My boyfriend has even ended up in the hospital with kidney and muscle problems from taking it... prescribed. I am scared and losing him to this terrible drug.
