You're totally not crazy. Heck, if we were all experts in battling head hunger, we wouldn't have needed surgery to begin with.
Just allow yourself to "feel" it, don't ignore it, but at the same time don't give into it. Just acknowledge it, think about what might be making you "head-hungry" and tell yourself you deserve to be healthy and successful more than having the ability to throw down a bunch of battered, deep-fried carbs that will NEVER love you back.
It's hard, but if you can start breaking this head-stuff down now, you'll have long-term success! And the hope of long-term success is why we have resorted to such drastic measures to alter our anatomies.
You can do this!
