My problem starting out on my weight loss was evening snacking. I started taking a walk every night after dinner, which helps me digest, and actually makes me feel satisfied so I'm not hungry the rest of the night. I made myself a rule: no more eating once I walk. Eat dinner, then walk, then done!
You might not want to take an evening walk every night, but you can still try and figure out some kind of guideline that will keep you in line when cravings start. It can be easier to stick to a "rule" than stick to the "I'm not really hungry" mindset.
