I have nothing but positive things to say about it! I am using the visualisation CD and find myself saying things to myself during the day like "I run like a child at play"... just out of nowhere it pops into my head and makes training more fun..
I am also finding that I am not thinking about food as much and like the CD suggests "food is just there". I am craving nurticious fresh and healthy foods and my body feels great.
I am sure about the idea that you stop craving junk when your body is properly nourished.
Hope that helps!
