Does anyone feel mental desires for unhealthy foods? How do you cope?

Often, even after having a lovely dinner of lamb chops, mixed vegetables, and a spring mix salad with bacon, I find myself mentally longing for a Domino's pizza with pepperoni, green peppers, mushrooms, onions and sausage. Or Häagen-Dazs strawberry ice cream. Or Miss Vickie's potato chips.

After my dinners, I feel full. And everything has been delicious. I love bacon-mixed-salads so much. I feel like the wish for foods that will make me slow, tired, overweight, physically weak, unhealthy and reverse my progress is mental rather than physical.

How does one face that? Currently, I just blanket myself in negative reinforcement -- I don't want to be out of shape anymore, I don't want to be tired and stuffed in the morning, I don't want sugar crashes any more -- but I wonder if you veterans and experts might have attitudes that are more positive than restrictive.
