Definitely need to talk to the prescribing doctor, as you mentioned, and be honest about it. There isn’t any scientific evidence to this, but some people feel that amphetamines are stronger and easier to abuse. Adderall is the main stimulant taken by those without ADHD that want ultra focus for studying and such. A methylphenidate may reduce your chances of addictive behaviors — you’d probably have to try it to know.
