you need to0 present to the doctor your concerns, why you think it would be beneficial in your case, and the positive things it could do to your life. If you are educated about a drug chances are the doctor wont have to many problems trusting you. Don't play dumb.
Personally I Love and find Dexedrine to be the Best ADD medication out there. A few bad things about this is tolerance, and the fact BARR is the only maker right now and let me tell you the binders in the 5mg pills, KILL the stomach to the point its almost making me want to purge at points but its worth it. A better choice Is XR Adderall in the am and the Dexedrine after just to boost you. I am going to call my doctors office tomorrow and set up an apt. I just find that 45mgs of damp, isn't all that stimulating by itself, and doesn't benefit me to much during a long day at school, or doing work. In order for a focus to happen I need a little bit of a stimulation that Dexedrine doesn't ALWAYS provide even when I take higher doses towards 70mgs-60mgs. Its just the levo amp in Adderall that helps with the wake me up so I don't fall asleep through this lecture. Not to say Dexedrine doesn't stimulate it certainly does, but not always to my liking. I know my doctor will be willing to help.
