Boo,
You might be like some of us. The artificial sweeteners trigger the cravings. Try to get off of the Aspartame and all artificial sweeteners for a week and see how it goes.

At night my cravings would drive me crazy! So I started making whipped cream, no sweeteners. I would eat 1/4 cup and feel like I'd just treated myself to something heavenly. You can put in bits of a vanilla bean.

I found that my energy level went up when I first started and I had some trouble getting to sleep too. I understand what you said about your breakfast. Been there, done that, glad those days are over...
