I only had the tapes for about two weeks and I, too, have noticed that the soreness is gone. I have used the one hour practice tape every day. Today for the first time I did the practice two times. I started the program hoping to find some relief for high blood pressure. So far, there's been no change. Strange enough, I quit drinking coffee. It didn't take much effort at all and I just don't crave it any more. Also, my diet has improved in that I don't overeat as much as before. And my clothes feel a little looser, but not any noticeable weight loss.
I will be really interesting to hear others experiences.
