HeartMath Solution for Better Sleep

First I will say this is written after another no sleep nite. So it is grumpy. This book has nothing new and was a waste of money. Maybe 10 pages out of 50 had a plan to use that included getting an app or another device. I did download the app and it seemed to work sort of. But no sound. I do not want to send my personal info to that "cloud" or have researchers use it without telling me what they found about ME. Not all data. I do not want to spend money on another gadget that has questionable reviews. HeartMath is good philosophy but is not useful in this book. I will stick with hemi-synch and "other" tools. Very dissapointed.

Recommend this to insomniacs and Type A exec’s to help monitor the stress levels and aid sleep catch upA good read
