angel,
the lapband definitely is not magic. It controls your appetitie, but not your mind. I had my surgery a week ago monday and my mind is still the same as it was before. You will still have your cravings, etc. It's just something you need to overcome.
Like today... I cheated and highly regret it. I was bored so I went up to Sonic and got me an order of cheese sticks. I ate four of them and felt like I was going to vomit all over the place. But, now I realize why I got the lapband. I've lost 20+ lbs now and my mind is set of my future. I hope to become married, have children, etc... that is what keeps me going.
Find a hobby or something that will keep your mind off of food!
