Cranial Electric Stimulation(CES) is a form of electro-stimulation that stimulates the brain to effect brain chemistry and thus mood. It is also good at helping with addictions. I have found it very helpful in treating Alcoholism. The electrodes are placed either on the mastoid process (the part of the scull below the ear), in the hollow behind the earlobe, or clipped on the earlobe. You feel the stimulation but it doesn’t hurt. It seems to work best when it is combined with acupuncture.
