I am on a diet, I'm walking past the baker and I smell the delightful smell of bread baking, and I look in the window and notice the cream doughnuts.  I love cream doughnuts!  The smell of baking bread is making my mouth water.

I hear a voice in my head that says "Wouldn't you just love a doughnut? Just one?  Then, I hear another voice or thought "You can't do that, you will never lose the weight that you really want to this week". You will never be able to fit in to that new dress or suit!
