Amino Acid? or Chocolate?

So, Charlie got this health supplement he ordered in the mail. He's into this sort of thing. He was explaining to me that it was a type of amino acid that was supposed to improve mood and affect dopamine levels. In short, he said, it was supposed to produce the same pleasant effects associated with chocolate.

So, you'd take this instead of eating chocolate? This feeling I'm having -- is this what they mean by "cognitive dissonance"?
