Had my first session of this today. I've been asked several dozens times how it was - fine is my answer. Fine has to be the answer, everybody seems to think it is wonderful. They've had it chiropractors and it just pops their neck right into place. Well, I think it sucks. I've popped tylenol, developed an addiction to Salonpas in addition to the meds that I normally take.
Worse than that, if it doesn't work it is on to needles in the spine guided by x-ray or surgery. I'll stick with the rack thanks.
