Over the past 16 years, I’ve never witnessed adverse side effects from facilitating my Positive Auditory Stimuli Technique. The only negative results I’ve seen on rare occasions are a purge of emotions, such as crying or anger, vivid dreams or pressure headaches. These generally subside within 24-48 hrs. It’s the unconscious brain’s way of releasing suppressed emotions and feelings. The pressure headaches are the brain being resistant to the new changes.
