You really can psyche yourself out, believing cucumbers, tomatoes and mushrooms are the most delicious things on earth and eating them is almost as good as chocolate. You can add fat-free yogurt and relish with some garlic, onion and chives to red salmon, put it on a whole wheat pita and think you’ve died and gone to heaven. You can actually get to where you have to force the last bits to make sure you’ve had ENOUGH for the day. And if you’re faithful all week, you can even have a few drinks over the weekend without totally screwing up.
