Query: Sound Medicine: Brainwave Massage

This is a great CD. I have used this CD and others by Dr. Thompson to decrease stress, help me relax, help me feel peaceful and help me fall asleep. Other brainwave CDs are energizing. I created a whole class topic after listening to a "Insight and Intuition" CD, and the class was good, if I say so myself. These CDs are better than drugs!
