If it makes resisting any easier, one time I let my brother eat all of his Halloween candy in one night because he gave me the sad eyes and he threw up about fifteen times. After that we both agreed that it's probably better to divide it up. We used to do it so he'd come to my bedroom door with his little pumpkin to trick or treat, I'd give him whatever I'd given him for the day, and we did that until the candy ran out.
