In our first report, we showed you how kids play a different kind of mind game, to cure their hyperactivity.

Today, at the University of Utah, an alcoholic and drug abuser, is doing the same thing, to kick his habit. Science Specialist Ed Yeates reports.

Terry is getting hooked up to take a trip. But this time, the trip won't involve drugs or alcohol. Terry has learned how to retrain his brain waves so he can walk away from drugs and alcohol.

He listens to a tone. That's sort of his audio pac man that tells him if he's in control - strengthening his alpha and theta brain waves.

Dr. Corydon Hammond, a University of Utah Clinical Psychologist says, "Alcoholics and children of alcoholics have a deficiency of alph brainwavaes. But when they use alcohol there is an increase in alpha brainwaves."

Researchers say that's why Terry is learning how to increase his alpha brainwaves on his own, without a drink.

His goal: to stretch the alpha brainwave activity as far as it will go. He explains, "I've been trying to be sober for two years and the last nine months--almost ten months--I havean't had a desire."

Terry has to work at it. He doesn't always have the machine to listen to the tone. But when he has the urge to drink or use drugs, he stops and plays the game in his mind - imagining scenarios of how he should react. "Running across people and stuff from my past that I did drugs and alcohol with, and just saying 'Hi, good to see you. Goodbye.'"

Every scenario increases alpha brainwave activity--without the need for a drink.
