What Adderall starts to do after you get a little too into it. It subtracts weight, money, time, sleep, patience, body temperature, and attention span. It "subtracts it all."
Prescribing doctor: I'm going to prescribe you Adderall, to help you focus and give you more energy to complete your tasks.
Patient: Thanks, doc. Anything I need to know?
Doctor: Yes. If you abuse it, it'll take everything away from you that makes you human. It'll give your skin the cold, slick sheen of a lizard, and your mind the attention span of a grasshopper. You'll forget about your friends, food, showers, why you even asked for this in the first place.
You'll be tore up from the floor up. You'll need a check up from the neck up. You'll go from Adderall... to Subtractitall.
Patient: *already stuffing script in his pocket, walking out the door: Ah, gotcha. Later, doc!
