I've used EFT at a surface level using only free materials from emofree.com for a couple of years. I decided this month to deepen my understanding and use of EFT, so I ordered all 3 DVD libraries. It has been tremendously helpful to view the 2 Basic Course DVDs. 

Within the first week, I was able to help my family and work colleagues quite a bit more than before. For example, I picked up my 14-year-old daughter from her dance class one night last week. She asked to set an appointment w/ Greg, our chiropractor. I said, sure, we could do that. I asked what was wrong. "My hips are tight." So, I suggested we try EFT. We skipped the setup, and did a few rounds of EFT short cut. I added 9-gamut at one point, I think, and we finished up with 1 floor-to-ceiling eye roll. In that 10-minute drive home, she tapped the tightness in her hips down from an 8 to a 0. At her suggstion, we checked it again after she was up and walking, and it rose again to a 1, which we quickly took back to 0 w/ the eye roll again. 

This daughter of mine responds much more quickly to EFT than I, who suffer from some chronic illnesses. But I'm learning to trust the process much more and we're having more success.  Greg, by the way, is keen on tapping and very excited about the exploration; he's not resistant, even though he may lose a few office fees. He is a wise enough healer to not practice medicine that way.
