I have encountered a number of people who are willing to try Emotional Freedom Techniques (EFT)/tapping, but because they don’t get earth shattering results right away they give up. There are many times issues can be cleared up right away, but that is not always the case.
Here is a great example, by Lynne Shaner, of the power of tapping when it is applied in a systematic way and applied to many different aspects of the issues. In this example she uses tapping for the emotions she is feeling, the medical treatment she is receiving, and for the cravings. This is a model we can all learn from.
