Drum up some willpower

Under the spell of that peppermint bark you co-worker brought to the office? Before you succumb, try this simple trick: Place the thumb and fingers of one hand on your forehand, a half inch apart.

Tap each finger one at a time, once per second, telling yourself, "Hold on." Wait 15-20 minutes (return phone calls, check email), and the craving will disappear, according to Tufts University Research. Sounds crazy, but it works.
