My sister's chiropractor does NAET treatments, and it really works well, from their experience. She has a friend who has a great success story with it. Her chiro actually has quite a story. Mind if I share??
His family was in a bad car accident, but no one was badly injured. But ever since the accident, their daugher became allergic to everything. It turns out, that everything she ate or put in her mouth after the accident (just that day) she became allergic to. And it was really weird stuff, Like plastic eating utensils and weird foods they didn't normally eat but did that day for some reason. so anyway, they figure out the connection, he hears about NAET, gets trained, treats his daughter, and viola, she's healed! Instead of leading a life of being allergic to everything, she's actually normal again. Kewl, huh?! And he sees great results with his patients as well.
It is impossible to understand some things, and NAET is one of them, I think. So if it works for you, then go for it. Give it a try--it can't hurt anything, right?!
