Well, the first step in any process of change is identifying *what* you want to change, right? Before you didn't know why you were slipping and now you do! That's a great start
So, now, you need to put a reminder on your calendar right before the time you ovulate. Depending on how you prefer to address it, you can write something cheerleadery "YOU CAN DO IT!!! STAY STRONG!" or something more clinical "ovulation is happening, watch for sugar cravings and add fats!" just to remind yourself that it's happening. Make a list of the WHYs you're doing primal and re-read it during those two difficult weeks. Plan a couple of really amazing meals during those two weeks. If you think it will help, plan your food out a little more during that time and for the love of Mike get EVERYTHING out of the house that's a temptation. Then, if you want sugar, you have to get dressed, into the car, and GO somewhere to get it and it might be less tempting or at least easier to put off.
Lastly, remember, most intense cravings last just a few minutes. I know most of us try to deny the craving, ignore it, etc. but I'm finding that if I have a craving, if I then let myself fully experience the craving, it goes away much faster than if I fight it.
I hope that helps
