Have to agree on the efficacy of EFT and it's effective use for various situations and purposes. I have used the very simple and basic tapping exercise for all manner of purposes,like developing an intuitive trading mentality, sports visualisaton, health problems, and anger management. Whenever i had privacy I tapped on the basic energy meridian points with my fingers, but I can tell you that whenever i was in public or wasn't alone I mentally tapped with open eye visualisation and the results were still effective.The important criteria is your emotional output that triggers the energy meridian points as you vocally or mentally declare the proper affirmations.There are tons of EFT vids on Youtube and I urge you to check them out.I will also try to upload an effective practical ebook on EFT.
