Maybe you just need to practice NOT eating marshmallow. Lay out one marshmallow and try not to eat for X seconds. Once you reach that X seconds, add another marshmallow. Keep doing it until you can't do it. After recording the number of marshmallows you ate, you try for bigger number of marshmallows next time. However, I never tested this. So if you ever try this idea, let me know how it goes.
