To dopamine

I. O fair dopamine
wondrous molecule, so cool
even gets you high.
II. Reward, punishment
in dopamine highs and lows
a complete package
III. Tasty dopamine
the umami of my brain
why can’t you hate carbs?
IV. Feel the pleasure and
the pain, wrong motivation
dopamine, habit
V. “Neurotransmission”
sad how these long science words
will ruin haikus
