I'll toss a potato into this pot. You can also have two forms of craving: craving paired with ignorance (which i think of as hopeless craving) and craving paired with awareness. If I know that craving is dukkha, then over time mind will be conditioned to crave less--seeing diminishing returns as non-productive. If I don't know this, that is, if I'm ignorant, I'll continue to think if I indulge my cravings I'll eventually find satisfaction. The problem is satisfying cravings does work--for a little while. Most alcoholics and drug addicts would still be using if it wouldn't kill them. And if it weren't for my diabetes, I'd still eat a box of Oreos at a time. But I know better.
Reality just isn't constructed that way--too much of anything will probably kill you. All cravings are dukkha. The Buddha wanted us to examine our mental and physical states very carefully so we see unwholesome actions produce undesirable states (ref: Kalamas Sutta). I don't really care what a bunch of Zen guys who lived long after Buddha said about it. Buddha pretty much spelled it out. No offense intended to you Zennists.
