Fundamentally there is a sense of not wanting to 'miss' anything, I believe that was the original force behind 24hr news channels, you watched because if you didn't then something could have happened HOURS ago and you wouldn't even know it yet.
I have a slightly different problem which is reading too much. It is embarassing when you miss your stop on the train because the article you are reading has distracted you. I also am something of a completionist when it comes to books, so I find even when I don't "like" the book I'm compelled to finish it.
I'm the same way. It's bad enough that I can't read on the train because It's guaranteed I'll miss my stop. I can't read in the evening or I'll be up till 4am finishing the book. I limit my reading to times when I have an open stretch of several hours to avoid it colliding with some other appointment or something.
