If it's distracting you that badly, then there are two things you can do:
1 - Go to the grocery store and get a frozen Lean Cuisine or WW pizza and eat that. It will help with your pizza cravings and possibly make them go away.
2 - If it HAS to be Domino's, then order a small pizza. JUST A SMALL PIZZA. No bread sticks. No cinnamon things. Just the pizza. Take out two pieces and set them aside. Throw the rest away. If you don't have the willpower to throw the rest away and not eat it then do something to destroy it first - squirt dish washing liquid on it. Pour 1/2 the salt shaker on it.
Eat the two pieces. Slowly. Enjoy them. Savor them.
And then drink lots of water to help flush all that salt out of your system.
Every once in a while you just have to give in to the craving in a REASONABLE way. If you let it go, you'll decide "oh the **** with it" and wind up binging on a whole pizza and breadsticks and cinnamon sticks and then you'll feel guilty and the whole vicious cycle will start again.
Part of learning to eat healthily for life is learning to deal with cravings and learning to find ways to keep yourself from throwing in the towel. I know for me, if I forbid myself to eat something every again, I'll immediately want more of it. But if I say "I can have whatever I want, just in reasonable quantities" I often don't really want it any more.
That would be my advice anyway.
