Have you found a place you think you will be accountable to?
Being convinced that random eating is not your friend helps. Also knowing that your familiar urges will come even though you don't want them to! If you keep giving in, you make them stronger. It also helps to plan good meals that you will look forward to so that there seems to be a payoff for waiting. Though most diets drop you down quickly in calories, it's actually better to start with bigger meals until you are used to structure. Then you can taper down your amounts. This takes weeks or months, not days. Try not to be in a hurry! But do whatever it takes to stick to your plan. Divert yourself by doing pleasurable or productive activities no matter what. You will feel better not eating and you will have the payoff of pleasure or peace for accomplishment. These will help replace the rewards of food.
