Bart Bromley: In a 1993 study, individuals who said that they were in love had their brains scanned to show neural activity. The map showed vivid colors over the gray matter, indicating clearly that this romantic love phenomenon activates a flood of dopamine in the caudate nucleus in exactly the same way that cocaine and nicotine affect the brain, meaning that love is not an emotion as is usually thought, rather, it's an addiction. When these chemicals are released in our brains, we feel giddy and euphoric, so much to the point that, we can be so in love that we don't have the desire to eat or to sleep, so it feels good when you have the drug, or the love, but, when it's taken away, you hurt.
