Hi Lori,
I've had some affirmations work really fast -- others are still working
I think it depends on what you are working on and how deeply rooted it is.
EFT works on the premise that we have energetic blocks. Saying what bugs us while tapping a specific point reverses the polarity of that energy flow, clearing the block.
I've never used the EFT while saying affirmations, I've just used it the traditional way.
I think the EFT works faster because it is physically removing an energetic block, where the affirmations are putting down new neural pathways in the brain.
But then again, I think it depends on what you are working on. I've had affirmations work to clear some things that the EFT didn't. :::shrug:::
