Freshly sprung from my monogamous LTR, I had no idea how vulnerable I would be to the onslaught of chemicals your brain releases when you're attracted to someone. These chemicals are responsible for every single people-in-love-are-crazy-fools song, movie plot, and Shakespearean drama ever written. They stimulate the same area of the brain that lights up when you snort a fat rail of cocaine. This state of mind, limerence, is a biological relative of obsessive-compulsive disorder. If you are an addict, or perhaps have the sort of low-dopamine, low-serotonin brain soup best served with a side of SSRIs, you are perhaps more sensitive to the mind-altering power of limerence. And if you are a romantic, you are perhaps more likely to label this heady, overwhelming sensation love. Being a low-serotonin addict with romantic tendencies, I had to experience many crashed-and-burned affairs to understand that for me, love really was a drug.
