Ivan, sometimes when I slip into that, the Bible on tape helps me. I just borrow it from the library for a week or two, and listen when I'm falling asleep or arranging things on my desk. Hearing it puts the statements in a different perspective. Instead of tiny words with tinier numbers and a lot of clutter, it becomes a cohesive story.
Another thing that helps me is to find a challenge, like a verse or teaching that bothers me. Then I use lexicons etc. to find the closest thing to the original meaning. It puts me into an active search rather than seeing the same scenery.

It's easy to kick yourself for slipping out of interest, but the important thing is to start fresh over and over. If God can forgive a mass murderer, He can forgive someone who gets distracted.
The problem might be something simple, like the repetition of seeing the same book. Or your eyesight might be weakening from being on the computer a lot (same distance, same eye muscles).
Playing games sometimes puts us into a repetitive state, a more relaxed set of brain waves. It's not always the game that you crave, but the feeling you get when you're playing. Adrenaline, relaxation, problem-solving, meeting challenges successfully.
It might help to try a fast of one thing that ties up your mind for blocks of time. Don't be angry with yourself; just pick up and start again. Repentance is a decision to let go and change. Immerse yourself in the Word whenever you can.
Thanks for your admission--most people don't talk about things like this.
