I have an IPF item myself and I agree with you that after a while it seems to fade. What you will notice if you take a break from using it is that you will start to feel the item working again. Take a 2 week break and see how it goes. I’ve done this myself many times. I think the body of the person using it gets used to the fields and integrates them to the point where you do not get the same results as when you first used it.
