Re: zapping your head?
Not that I would recommend this to others as there is potential risk.
I had basal cell skin cancer on my left temple, had a biopsy done which spread it. Rather than having several repeats of this problem, I decided to zap the lesions. I could tell that there was some effect on my eyes when I zapped the temple because I could close my eyes, apply the positive electrode, and see brightness being produced by the signal. It went away once the electrode was removed.
After a couple of days of zapping for 1 hour continuous in the MX mode, the burning sensation went away. I continued for a little more than a week of zapping. The lesions were gone. I did also later have two additional lesions on my forehead, zapped them the same and they were gone. Cancer free for almost 10 years now.
So, this was helpful to me but I do warn about the potential for possible damage to vision.
As a note, my eyesight was about 20/200 in both eyes at the time. It is now 20/20 in the left eye and 20/35 in the right eye. Most of this improvement is from eye exercises.
I would also like to submit this: If you zap your head and you have a reaction such as seizures, it is quite likely that you have some
parasite in your head that is reacting to the zapping. No proof but just my thoughts on the subject.
