I tend not to believe in any of these new fangled machines. They just seem to be a way for folks to make some money off us sick people. I had a "doctor" use that Vega machine on me once ( I didn't know what it was called until I saw this info ). He didn't know a damn thing about candida. I would feel more comfortable with the blood food allergy profile ( or just simple elimination and rotation ), but that's just me. :-)
