I should point out that the feeling exercise is not for changing or removing the feeling. It's for becoming aware of the power that is in feeling the feeling. To be used for both those feelings and emotions we term positive and negative. Try the feeling exercise when you're feeling high.
As for Using EFT we've been using it since the PhotoReading retreat. Id you get the Results Supercharger DVDs you'll find we are using EFT for positive results with PhotoReading.
