What's an "addictive personality"? You hear that all the time, and yet, how is it defined?
I was a smoker for a lot of years. I quit when I became pregnant with my son, and never really had any withdrawals. I think in my case, I smoked because I just didn't care enough about the state of my health. It was easy to quit because first of all, I wasn't that addicted to the nicotine, and secondly, I had a much more important goal in mind.
It's the same with the food. For a lot of years, I've been oblivious to the damage the food was doing to me. High blood pressure, varicose veins, cholesterol issues, bad skin and hair, digestive problems... the list goes on. If anything, I was addicted to the laziness of eating poorly, but I don't think I was addicted to the food itself. So easy to get a quick meal at a restaurant, and not pay attention to the quantity and quality of the actual food.
I could have started eating healthier years ago, but I was young, and thought I was immortal. It was always in my mind to get healthy... someday. Finally that more important goal appeared in my mind like the light at the end of a tunnel. I started moving forward, and haven't looked back. I finally saw the light!
