I was really impressed with my sessions with EFT. I experienced the very first ever relief from a migraine without help from someone else using these techniques. Always before, I had to have someone do acupressure for me--which worked, mind you, but if I got a migraine while alone, I was stuck with it.
That time, I zapped it with EFT, and (knock wood) I've never gotten another one. I could feel it being zapped--first there was a tingling in my head, neck and shoulders, then, like magic, it was just GONE.
I've also been using it on some other challenges, mostly small potatoes compared to the migraines, and it's been just amazing.
That said, it's not much help for physical conditions like sinus problems--finally gave up and got some antibiotics for that. I suspect the techniques have their limitations, which in my case, I prefer to respect.
