What is your Achillies heel in the food world?
This is going to sound odd for me, but a few years ago, I developed a strange addiction to McDonald's Double Cheeseburgers. They removed it from their menu many years ago, but if you ask, they'll make one for you. My wife was making me eat all of this heart smart foods, and every time I would run an errand that passed golden arches, I would get this itch, like a crackhead wanting a fix.
This is why I am scared to death of alcohol and drugs. It was hell getting off the double cheeseburger fix, but I did. I still get that tempting pull to go through a McDonalds Drive Thru when I pass one, but I let the feeling subside, let the sweating and heart palpitations pass... they aren't even good. It was just the quick fix thing.
