At the moments when you are happy with your life, the desire to escape from reality reduces dramatically. So I guess a high-level approach might be to optimize your life to be more happy, even if it seems like it would reduce your productivity, because you may get the side effect of procrastinating less.

I think most of my own procrastination has always had more to do with the desire to escape, and feeling bad about low expectancy/value of the work at hand, rather than the procrastinating activity itself being highly entertaining.

Being productive can feel terrible because it is a constant reminder of not just what you want to achieve, but also of the fact that you have not achieved it, depressing stuff really.
