Sounds like you need more protein early in the day. Be sure to eat breakfast. Snack on protein until you find what works for you. Carbs might trigger more snacking later.
If you must eat extra, stick to veggies. Green beans with a flavored vinegar -even season rice vinegar (which is sweetened) is better than the dessert stuff. Dried fruit and a glass of water or hot tea can really help curb the cravings.
Eat mindfully - not just pushing food into your mouth while watching TV.
Think about whether you want food or something else - is it emotional? How are you feeling?
A few weeks or adjustment is normal and you may go over but if you eat less than you did before & stay or get active, you will succeed. It will simply take longer.
Check out SP recipes - there are lots of options for snacks & meals. Variety will help and it sounds like you have a diet mentality when it comes to food. Celery & carrot sticks are ok but so is zucchini with hummus, hard cooked eggs, string cheese, soy yogurt, diet jello, frozen fruit bars, oatmeal or farina with PB & cinnamon, beef broth, air popped popcorn, edamame.
