I'm right there with you, in favor of giving it up. Only thing that keeps me involved is the wish to make my tech skills super-useful to society. Two points to clarify here:
1) It's smart to search for other toxic influences than EMF. Get rid of them all my friend! The Paula Owens page I linked to above lists them all. It may be a little extreme on some things, such as never cooking with plastic. But better to be overly pure than overly sick.
2) It's not about just shielding, it's about healing and nourishing. That helps fight EMF, strengthen areas of your body so the body has more energy to overcome EMF, create better feelings about life, and so forth.
So really "holistic" means, just be healthy and happy and that will help overcome EMF while you extend your life-happiness.
