It's always wonderful to hear from people that they've tried it and it works. I remember that strange feeling when first using it. (edit:)*The biggest obstacle to getting comfortable with it might even be a sense of 'worthiness'. (which might be a great way for someone to start tapping: on all those weird feelings/thoughts/certianties about why "it won't work", etc.) So often, we cover up an inner sense of lack with resistence. It can be a big brainstorm to tap on everything that blocks one from receiving the benefits of -say- EFT. :-)*
I'm very happy for you it's changed your life. Your experience can change others' lives too.
