Please, PLEASE consider your EMF exposure (electro magnetic fields). ALL the symptoms you mentioned are typiccal from EMF sufferers, Try to avoid as much as you can WI-FI, Cell Phone towers, bluetooth, 3g, Radio frecuency, microwaves. You shoul try going one week on holidays to a place with almost zero emf, a small valley away from big cities, and IM SURE you will notice the difference. If this happens, strictly consider protecting against your local EMF or living in a zero EMF zone for ever. Sad but true, thats what happened to me :S. Good luck
