SONICONTROL…play store app
Listen cell phones are extremely dangerous and are essentially a chip in your hand and transmitter to the one in your body…I understand they have become a necessity but if you aren’t using it turn it off…and put it in another room this will lessen the headaches…
ALL DETECT……. also seems to be a good app from play store…it lights up like a Chistmass tree when this thing is on….
I have also found that an ice pack on your head seems to help quit a bit in the morning…must cause swelling and it will help you think a little better…
Take a piece of Black tape and put it across the top of your phone flash and video camera….and see what happens for a day…???
More will be added
