Here's the fun bit though - I don't get "speedy" from the medication I'm on. Looking back with hindsight, when I was a teenager and snorting Ritalin with my friends, they got all silly and giggly, while I felt calmer. Was a sign I should've taken seriously. At the time I just thought I'd gotten dud pills.

But yeah, I think a good metaphor is that people with ADHD are starting at -1, people without are starting at 0, and then the pills add a +1 to both.
