I don't understand this. Does this mean that I could've caused the problems? It seems like that because ever since I started to use the ravo zapper I felt that I am making myself sicker day to day but I could not stop as I already started - I had to keep going, but after almost a year not getting any success (except of some Ascaris at 408 kHz) it could be that I've cause some dispersion or something really almost for an emergency surgery - that's how I feel.
What can I do? What is the device that you are using?
