I have the opposite problem. I think about food nearly all the time. It's what got me up to 295 lbs.
I'm down to 260 today. Still got a long way to go, but I'm getting there. Getting medicated makes me feel so much more in control of my impulses. One of them being the impulse to eat all the time. Now, I don't feel hungry nearly as often, and if I think about food, I consider whether I feel hungry, and if I don't, I don't eat.
