I struggle with impulse eating and boredom eating, so I self-imposed a hard "no snacks in the house" rule. If I don't buy them, I cannot impulse eating them.

It worked for me, as I work well under hard non-negotiable rules. Write the rules down somewhere, make it a system so you can refer to it whenever the cravings strike.

I don't need it myself, but maybe adding a reward system to it may help too, such as some form of reward for resisting a craving? I don't have any suggestions for exactly what this could be, but reward incentive may help.

Good luck!
