Panda, my suggestion is that you should try either the cream cheese clouds or Dr. Attia's ice cream from our recipe group. Also, I saw somewhere (it may have been here?) where the person sauteed the stuff she wanted on her pizza (mushrooms, onions, peppers) threw in some sausage. then put some warm red sauce on her plate, put the sauteed stuff on top, sprinkled it with cheese and put it under the broiler for a minute to melt the cheese. So it was essentially a crust less pizza, same flavors different form.
Most times I think we crave something because we are missing a nutrient or something, but then there are times we crave something just because we can't have it.
