There's a synergistic effect when two people work together tapping, that makes it more effective. And when someone taps ON you, its more effective again. At least that what I've found with clients. So part of it is needing to be more persistent on your own, and do more rounds. But part of it too is the art of it, knowing what to tap about. More on that next time.
That would be great to have more articles on EFT by different people.
