DNRS has an extremely high success rate among people who commit to it as recommended. Rather than chasing symptoms, it treats the conditions at their source. 

Here’s a very brief explanation of how DNRS works:
1.    The symptoms of these conditions are very physical and very real.
2.    It’s not possible to control the symptoms and the symptoms are not "all in the mind".
3.    But the brain can change (both for the better and for the worse). These conditions are said to come about through a brain injury, probably caused by the "perfect storm" of factors including physical (viral/bacterial/chemical etc), psychological or emotional traumas. But with the right knowledge and practice it’s possible to change the brain back to its original state and therefore recover. 
4.    A healthy brain is of course the most important foundation of good health, so healing the brain after such a brain injury is essential for full recovery and completely different from chasing symptoms.
