If you have not already, check out the Earthcalm and Earthing products.
I am EXTREMELY electrosensitive and cannot be around Wifi at all without my nervous system going into overdrive. I recently purchased the Earthing starter kit, and the Earthcalm Omega Wifi product, and they have had a DRAMATIC effect.
I am still affected by the Wifi when using my laptop, but the effects have been reduced by about 75%. I have no other choice for internet access so this works for me. I still can't spend hours and hours on this thing, but that would not be good anyway.
The Earthing products are amazing also. The first time I plugged in the Earthing pad, about 15 minutes later I felt a rush of blood to my head, and a sense of calm came over my body like I have never felt before, this was while sitting in front of a computer screen!!, I was so amazed, I cried.
That night I slept with the Earthing sheet, and woke up early, and more refreshed than I have in many years. I called my my Dad and he thought something was wrong because I was up so early!!
Obviously the real solution is not have all this dreadful radiation surrounding us, and to be outside on the actual ground as much as possible, but these products work,
and no I do not work for any of these companies, just passing along my experience.
