This is a "must read" article! A short quote:
Most people sharing space with you at that moment would have no idea of the epic battle going on inside you as you ferociously and desperately debate yourself over your upcoming food choice. Sometimes we win that battle, and sometimes we don't. We may reach for the pie, smile at the person standing next to us, and say, "Oh, well. Just this once won't hurt." And, it doesn't. If anything, it brings on a full-body wave of release. We actually sigh out loud sometimes with the bliss of it. Our shoulders drop as our muscles drain of tension.
Our eyes may even glaze over a bit as we go to our happy food place where our taste buds sing and our heart soars. Dopamine, after all, is the very same chemical that is released when we fall in love.So, it's true, then. Just this once really doesn't hurt at all. In fact, it feels really good. However, when I close my eyes and picture myself having that bite of pie followed by the full-body melt, it's hard not to also imagine the images we've seen of crack addicts in the movies. Just picture the wild-eyed, jonesing addict on the floor, leaning up against the dirty wall of the crack house, tourniquet tight around her upper arm. She inserts the needle into her vein, pushes the plunger, and we see that same body melt, the same release, the same eye glazing we ourselves get when we eat the pie.
