It seems like such an obvious/silly thing, but I have found that having a nice large desk space with a good chair and lighting with no single computing device on it is a pretty powerful thing when you've become addicted that way. At least it's useful as a place to read books and magazines, and to sketch stuff on paper.

For the past 25 years, my best (and often only) desk at home has had an Internet-connected desktop computer with the largest/best screen I could afford placed directly in front of the chair.

I've been trying out different placements for this non-computing desk, but I think the best place may actually be just next to the main "computing" desk. Too far away and I end up not using it that much.
