Two stories on how my friends got a scrip.
#1.) Comes in, acts completely normal, trying his best to appear that he doesn't really need Adderall, and just nonchalantly mention to them that he had trouble concentrating, and it was messing with his productivity. Told him he might have adult onset ADD based on commercials he's seen.
#2.) Ballsy approach. Comes in and acts slightly twitchy and weird. Tells the doc that he was diagnosed by the family doctor when he was still young, but his parents didn't want him on any medicine. He said he experimented with Adderall and that it really helped with a lot of his problems. Told them if he doesn't prescribe them he'll just get it from his dealer anyway, but that he'd rather solve his problem professionally.
Be creative and Adderall may just be yours.
