Went and looked it up for ya, mostly because I wanted to read it again:
Quote:
"Scientists have found that romantic highs are fueled by mood-lifting neurotransmitters such as dopamine and norepinephrine. However, the strongest cause of euphoria is a hormone called phenylethylamine. This particular hormone is released during fresh infatuation and resembles the chemical make-up of morphine. These neuro-chemicals distort your sense of reality. You are, in essence, under the influence of drugs.
