Take one everytime you pass, wrap it in a paper towel, and drop it in the trash.

Plenty of "normal" people do NOT feel the food calling the same way you do, so I think it's fair to help get it out of the office. Or try being one of those "neat freaks" who is terrified of germs and won't leave anything sitting out for more than 30 minutes... oops, I threw it away... I thought you were done.

Or, work to change your mind about whether or not it is even tempting. I know this may sound impossible. But that stuff is about as good for you as eating soap. You know where it brought you. You don't HAVE to eat it anymore--you know if you start, it'll be WAY hard to stop, too.

You don't HAVE to be tempted.
