If Adderall is illegal to prescribe in the UK please don't try to buy it. There must be other drugs they use for ADD over there that would work as well as Adderall. Do you have ADD symptoms? In other words is your bulimia a symptom of ADD or ADHD? If so go see a doctor there and talk to them about it. It's worth a try. Going on a medication like Adderall without a doctor's monitoring could end up leaving you with even worse problems than your current one. Hope you can find a doctor to help you.
