Query: Not satisfied

I bought the book about 1 year ago and can't understand why it hasn't helped with some of my medical conditions. Lower back pain, neck pain, muscle spasms, weight loss and general stress. I did the exercises 2 times a day for 4 to 5 months. I never got any good results so I stopped doing them.I read all the testimonals of the great relief from various problems and am unsure why it hasn't helped me.
