You will find the cravings for all those snacks will go away. I used to be terrible about snacking on cookies, chips, nuts, cheese, lunch meat, you name it. After I got used to eating good, filling meals I no longer have the urge to snack on anything. I threw away some moldy lunchmeat the other day--that stuff never used to last a week! If you train yourself to only eat at meals, it goes a long way towards calorie reduction in the long run.
