Query: Really works, but you must commit

This book helped me get out of chronic pain, and dependency on chiropractors for "feeling normal". It took a while, and regular commitment, but I'm a believer. The book is great, but you can also order personalized "menus" from the Egoscue Institute itself that are very helpful and affordable (just in case you have a pain issue that you may not know how to address with the book). I believe that Pete Egoscue is definitely onto something. The bones do what the muscles tell them to, plain and simple. I found it easy to look up my areas of pain, and follow the routines in the book, then graduate to the next routine as things evolved and changed.An added bonus is mental relief. Seriously, once you get out of chronic physical discomfort or pain, the biochemical relationships between your endocrine system, your neurological function, and the way your body feels gradually improve in time. Everything is connected.
