Yes, I have had those impulses. Years ago when we used blackberries, I had one that every time a notification came in, a little red light in the corner would turn on and blink. I remember that I was always checking to see if that light was on. If I was watching a movie, I would constantly look at my phone to see if that light was on. To start a change that will benefit you, you must recognize the moments in which you are using your cell phone or phone out of boredom or anxiety and not because it is really necessary. When you detect that, you should do something else, something simple, to start with.
