Most people here report that, after going vegetarian, the mere idea of eating meat is gut-wrenchingly disgusting. I remember one poster went so far to compare animal flesh to feces. However, this is not universal. Some of us still find meat appetizing, as we did when we were growing up eating it.
I don't know if you would call this a "craving" though. For example, when my omni friends have meat leftovers that are going to be thrown out, if it is something suitable as food for my cat, I have no trouble refraining from eating it myself as I bring it home for my cat.
In my experience, sometimes when people drop meat and fish from their diet, they replace it with more of whatever else they were eating- or with some other foods that are nutritious, but do not nutritionally replace meat. If I tried to live on salad and vegetable stir-fries, for example, the rumbling from my hungry stomach would make the walls shake. Meat isn't really unique, nutritionally-speaking; you just have to know what it provides, and find other foods that will do the job just as well, or maybe even better.
Your post didn't come across to me as ignorant or condescending at all, by the way, and I hope my reply doesn't either. Welcome aboard!
