WOW! I am very pleased with my results so far! I have to admit, I was slightly skeptical if this would work or not, but I kept an open mind, I have received my unit yesterday, and after a 20 minute session, I felt a bit odd, I couldn't put my finger on it, but I felt...changed, now for the last 5 or so weeks, I have been chronically sick, I don't know what it is, but I had lung infection, lots of mucus in the lungs, in my nose and air way, made breathing not so nice, this morning I woke up, and I noticed some thing, my lungs are clear! almost like magic it cleared all up! all this after one session!! amazing!
