My urges are hardly ever for a "full stomach." My urges are more along the variety of, "I'm worried about making goal in Q3, so, therefor some Chinese food will make me happier!" Or, "Wow, what a great meeting I just had, I think I'll grab a club sandwich and a pint of Guinness to celebrate."
Thankfully, my sweet-tooth desire is becoming more and more a giant bowl of cherries!
But, the big battle is ignoring my desire for food and drink I have deemed pleasurable for the past 15 years, or fighting through and eating a completely nutrient rich meal knowing that afterwards, when I am full I will be much happier and have lost all desire for the original craving, be it a martini or some pork & crab meat dumplings!
Mind over matter. A saying often used, but not often used in practice.
