One more cheat tip

Chew any kind of mint gum, swish mouthwash or brush your teeth!  The flavor of mint will help deter your desire to eat.  Promise.  There are no excuses with the option of a million gums, travel size mouth wash, or the Colgate Wisps (disposable toothbrushes ready to go).  I swear by this technique!  It won't work forever, but definitely helps!
