"For many years, (since treatment for Hodgkins disease and treatment) I have had serious trouble sleeping. The fear of not sleeping has kept me awake and greatly affected the quality of my life. I have tried so many things, until now nothing really worked. Since April, when I did the detox, I have been sleeping well, without those nasty, panic-y thoughts! Because of Dr. Leaf's teaching, I no longer feel like a victim of my biology."

"I just want to let Dr. Leaf know how much her Neurocycle program has helped me. I am on the 19th day of my 2nd cycle and there has been such a tremendous change in my thinking. To be honest I was not sure it would work but this has been truly life-changing. I just want to say Thank You for the work you are doing.I have struggled all my life with anxiety and now to be able to walk in freedom after 58 years is truly a miracle."

"This app is a life changer! I discovered and used this program while I was a police officer. I walked off the job burnt out, depressed and totally broken. This program was a staple in my healing and getting myself back to the job. I’ve recommended it to many."
