What is EFT?
EFT® is very soft, low risk therapeutic technique established by Gary Craig. It is rooted in the ancient, traditional oriental practices of meridians, same root as acupuncture, acupressure. Basically we are replacing the needles or pressure holding with light tapping, just to energize the meridians. In EFT® we tap all major meridians, this way where ever a thought crystal is held will be released, we don't have to find the exact location. Very easy technique. Once you understand the method you can help yourself in any minute of the day.
How does it look? What to expect?

When you work with a practitioner they will interview you for a good half an hour or more to find out the most about your problem and the emotions behind it. They are also listening for sentences that seem the most charged, filled with emotions or that repeat as a pattern. Once the story is laid out and they have a good picture of what happened, and how and why it bothers you they start the session. They hold your hand and tap on your points and you repeat the sentences after them. They will start slow, first acknowledging the superficial layer of emotion, tapping until each and every one of them are heard, said, experienced, held and released. Once there is a good rhythm and rapport with the practitioner the sentences usually come naturally and sometimes they check back with you if that expression is what is the closest to your experience. If not, you can always correct or come up with your own sentences and follow your emotions. You as the client are supposed to stay present with your feelings, have one part of you stay online as a witness so you are not reliving your trauma but releasing it. The tapping continues until we reach a resting point, balance and certain calm. When the same sentences don't bring on the same emotional charge but you can say them, feel them without the nervous system reacting to it, there is time for integration and come to a pause. Later on we can check again if we really cleared out everything or there is more or something else have come up.
Generally the fist session in 90 minutes at least because of the interview at the beginning. Follow ups for the same problem or related issues can be shorter, but overall a 90 minutes is a comfortable time for both the practitioner and the client to feel not rushed. It is not a long process, some topics only need one session, some topics may need a few, ultimately it depends on the clients honesty, openness and energy resources.
