If at the end of the day you're "starving" even though dinner is done (so are breakfast, snacks, and lunch, too) whatever you do - don't start another meal!
Drink water. Eat an apple. Log onto your computer and tell your temptations to people who understand on the Beliefnet Spiritual Weight Loss board.
Call a friend. Write a letter. Go for a walk. Start work on that scrapbook you've been meaning to make.
Brush your teeth. Go to bed.
