what about filling it with candy you don't like?
I know for me, I wouldnt be tempted by peanut m&m's, allsorts, bridge mixture, mint leaves, snickers bars, mr goodbar, dark chocolate, anything chocolate flavored like fake fruit , etc.
There must be something you don't like. Fill 'er up!!
And if you like everything, put the thing you like the least. Even hard candy I could binge on. HAve you tried milkfulls? MY mouth is watering just talking about them. I;m an avon girl and I put in a hard candy with my customer's orders. Used to buy milkfulls, NOT ANYMORE! LOL
Now I get campinos or werthers. I don't hate them, but they are very easy for me to resist. BUt the milkfuls had a vanilla fudgey centre
LOL and tended to disappear fast.
