Education, Learn, Learn, Learn!
My advice is to educate your self as much as you can, as the adhd medication politics stands right now is a mess. The best thing you can do is to learn about stimulant medications and how they work in the human system. Once you know how things work you can make good arguments to your doc. Best thing is if you make him/her understand that not giving you the medication you need is unethical, that way it becomes a personal morale situation to him/her, witch improve’s your chances of getting treatment you deserve and need.
Best of luck to you.REPORT ABUSE
