I followed all the advice in this book. I was really positive. In truth I completely ignored my illness and went climbing in the Tien Shan, the Alps and locally in Cumbria. After each exertion I suffered an increase in spasticity and other severe neurological symptoms. I am now told that the initial viral infection has caused permanent damage to my autonomic nervous system. When I was first ill I was told it was "all in the mind", the approach advocated by Ms. Chalder. Now I have had surgery in the form of a sacral nerve stimulator. I am also waiting to see a neurologist as my consultant feels my happy go lucky approach to exercise coupled with my postural orthostatic tachycardia is causing hypoxia in my brain and this explains my problems with spasticity.
This may well be the most dangerous book on ME/CFS ever written. Charles Poser, the notable Harvard Neurologist defines ME as a vasculomyelinopathy. Chalder completely trivialises a potentially serious disease that if treated in the manner Chalder suggests can cause permanent damage to the brain. Read Byron Hyde's definition of ME, it will guide your physicians in identifying pathology and ultimately help you get appropriate treatment. Otherwise read the book and be ill and happy rather than happy and well.
