We all have an electro-magnetic field surrounding us- and that is why I hesitate to use the zapper. I even get bad effects from wireless phones-- including portable wireless phones.
What I would do - along with all the other alternative things you can -- is to daily "ground " yourself by walking 60 minutes a day. Also hold onto tree trunks-- even hugging a tree when noone is looking will ground you.
According to Kevin Trudeau in his book, "Natural Cures they dont want you to know about", walking 60 minutes a day will help restore the harm done to our electro-magnetic field. It is the only excersize that actually "grounds" us humans. Rebounding (jumping on a trampoline is also good-- for the lymphatic system)
Try a Reiki Massage as well- I didnt believe in Reiki therapy til i had one done to me this past May- Wow!! what an experience!
Also get out in the Sun every day- because the Sun's energy can heal your screwed up energy from that electrical device. Its' another way of grounding you.
When asleep at night, shut off all power from your circuit breaker.
Also, get a magnetic mattress pad, or magnetic seat cover for your car.,etc. Magnets help in healing this sort of thing.
Limit your exposure to the computer- as well as TV and spend more time outside on the Ground than near all the electrical stuff in the house.
Also, id' get magnetic bracelets and experiment with them- seing how your arms/wrists, etc., feels after a day of wearing one. Put rocks in your pockets- that may help ground you too and help with your EMF.
I also would get your metal fillings removed- and replaced with composite fillings. As well as stop wearing watches and any metal you may have worn.
Even metal eyeglasses-- switch to Zyl or plastic glasses.
