A cranial electrotherapy stimulation ("CES") device which generates electrical pulses is applied between the forehead and wrist area of a human being in order to affect electrical activity in the brain and thereby decrease the individual's craving for controlled substances such as alcohol and drugs and reduce anxiety, insomnia and depression. A portable cranial electrical stimulator is preferably attached to the arm area or about the waist of a patient. A first electrode is attached to the forehead of the patient, preferably above the bridge of the nose between the eyes, and a second electrode is attached to the wrist area of one arm, preferably at the radial artery. Electrical pulses having an amplitude in the range of 0.1 to 1.5 mA and a frequency of approximately 100 Hz are applied for at least 20 minutes at a 20% duty cycle between the forehead and the wrist electrodes. As a result, electrical activity in the brain is affected, in particular, the amplitude of P300 electrical brain activity is increased. Since decreased P300 activity is associated with increased patient interest in drugs and alcohol, the use of the CES in this way makes it less likely that the patient will desire such controlled substances.
