I wonder if it ever goes away...

It's 9:30 at night and I'm sitting and writing in my journal. Reflecting on the day. I've stuck to my meal plan really well. I've eaten clean all day. I've had plenty of protein and fiber and even carbs. My calorie count is right where it should be for the activity of the day. And I'm hungry.

I don't mean hungry as in I just feel like I could eat. I mean a physical, empty-stomach type hunger pang. It isn't logical. I've been back on my meal plan for 2 weeks now, and I've gone to bed "feeling hungry" almost every night of that 2 weeks.

I wonder if it ever goes away. Am I this big because I'm wired wrong and will always want to eat too much? Or did eating too much for so many years make me this way? Do I get to the point one day where I no longer feel these pangs? Or do I just get to the point where I can better ignore them?

I'm not asking this from a "feel sorry for me" position. It's more scientific. I really would love to understand more about what's going on in my brain, in my stomach, in my entire body.
