A few years ago, the wife of the Baptist pastor in my village looked very tired and seemed to be constantly yawning. I asked her about it, and she said she seldom could sleep more than three hours a night. When I diplomatically (I hope) asked her if she had things on her mind, she said she had bad family memories from her childhood and could not get them out of her mind. I asked her husband's permission to teach some basic EFT techniques.
Contrary to many opinions, EFT is not satanic. Dr. Still, founder of D.O. medicine said he thought the organs communicate with each other. If you have a bad experience, your brain communicates it to the heart which acts as a server and sends the emotions to the organs which answer back. Over and over and over. EFT is a simple tapping sequence based on the same concepts as Acupuncture. The Chinese figured this out thousands of years ago. EFT interrupts the over and over part.
It works on vets with PTSD. In the 90's, Gary Craig took a team to a California vets hospital and tried it on some vets who were still in there since the Viet Nam war. They sent several home within a week, to stay.
You can get all the info you need on-line, free. But, Gary Craig has two forms, one is called the Gold Standard, the other one is for space cadets, avoid.
Anyway, she tried it. When I saw the pastor, I asked if it worked, The first night, she slept till 10 am and he woke her up because they were all hungry. I asked him, Can't you cook? He laughed and said, yes, I can cook but I am not going to do it.

The Mexican man in action.
It seems too good to be true, but it is based on the human body, not nutsoidal spiritualism as many imagine before even reading about it. This is not spam, I have no financial interest in it. Craig does have videos for sale, but they are totally optional.
There is also videos specifically teaching how to do it for veterans with combat PTSD. If I had contact with vets, I would buy the videos, but I am in Mexico.
