it turns out that my physical symptoms are secondary to emotional ones (anxiety) so Rife is not the best way for me to go ( I'm trying EFT).
However I believe that if you have a truly physical based problem then it will sort it (it did very quickly with my verrucca).
It's certainly worth giving it a go as a pc based system is really cheap (get yourself some TENS pads to make application easier).
Also another interesting site is Bruce Stenulson's (http://www.stenulson.net/althealth/)with different ideas on how to use the technology.
good luck
