On that tangent: is there such a thing as a "dexterity-and-reflex-enhancing drug"? I don't think amphetamines do that, nor any nootropic I'm even vaguely aware of. "Focus" or "alertness" is one thing, but actually suddenly being better at competitive twitch games is quite another. Maybe an anxiolytic, actually—theanine?—if you wanted to prevent "yips." But otherwise...
