i quite like wellbutrin myself. perks me right up. just throwing that out there. i also use stratterra, and thats good too- clears up my head, definately helps me focus. don’t knock it cos it aint a stimulant. 
your post came off as super cryptic and hard to fathom, btw, and i agree totally about the dopamine stuff, especially if you’re of the addiction-inclined persuasion- stimulants might make you *feel* awesome, but odds are that you won’t produce anything of any real worth or note, or end up with a tidier apartment and more money, if they’re not what you medically NEED. you’ll just acheive SFA at hyperspeed, and confuse the hell out of everyone around you, then come down with a crash and end up pretty much where you were before, only surrounded with more half-completed and bewilderingly random chaos in terms of ‘acheivements’.
you want a stimulant? drink coffee?
