My son's grades were slipping and I was very concerned. He'd study, but he always had rock 'n roll music blaring. I've used Brain Sync meditation CDs for years and really like them, so I gave him the Total Relaxation CD hoping it would help. When I go past his room in the evenings now, I hear the soothing sounds of the Brain Sync CD. His grades are improving and he seems calmer. Our relationship is better, too, now that I can stop being the nagging Mom!
