When I was first diagnosed with gluten allergy, it was incredibly hard for me to keep cooking all gluten rich meals for my family. I wanted the pizzas, pasta etc... after awhile, the cravings went away and since I am in charge of cooking, I have made "me friendly" meals for the entire family, at times. -- Last night we enjoyed gluten free pasta dish, and it was well received by all.
I would say; this is your choice, your life. You choose to become healthy, unfortunately that means that you have to be in charge of yourself and your cravings

You know pizza is off limits; just think when others indulge on it, how you are strong and NOT gaining weight. you would end up feeling lousy anyways if you caved in.
Stay strong!
