I don't believe you HAVE to.
SW advocates that you have 1/3 superfree with your meals, and it is really good to speed up your weight loss but I believe you can do it without the 1/3 for your breakfast.
When I first started EE, the 1/3 was just a suggestion. I didn't do it for every meal, and still don't.
As long as it is working for you, I wouldn't worry too much.
