A head inside a snow globe is a pretty good metaphor for what it's like living with ADHD. The shaken snow globe is unmedicated, and the settled snow globe is medicated. Things become clear and you can "see" the things you couldn't focus on before.
Not exactly legal but it's pretty common to ask a friend for a couple doses. If you can find a good professional though I'd advise that. You can get a diagnoses and they'll have you try different meds to see what works well for you
