I finally decided to loosen up on the "Primal" a little. I am craving sweets. I don't usually, but it is creating a situation where I am eating lots of other stuff to satisfy the craving. So I went to a low-carb treat, that is not totally primal (homemade though). And it seemed to calm the afternoon beast.
I am not sure what is causing the cravings, but it is better for me if I just figure out a way to give in a little instead of using will power to try to hold it off, because eventually it will set off a binge, or set off a series of mini-binges.
