Taz, congrats on your commitment and good luck!
The sugar cravings do subside a lot. I was profoundly addicted myself. When I first went primal, walking by a Cinnabon felt like attending my best friend's funeral. That stuff rarely interests me now; it starts to look good if I haven't eaten in a long time, but then I eat something healthy (with plenty of fat) and I no longer care for it. A few times a week, I eat some fruit or some sweet potatoes, and this probably sounds crazy but those give me more sheer pleasure than all the sugary stuff in the world used to do.
So hang in there, brother. I remember being in your shoes and being skeptical that the cravings would ever stop. But they do, and it only gets easier from where you are now.
