You still won't be able to completely get rid of devices. They've already become a part of our modern lives, something that's firmly woven into them. I don't think you need to give them up, you just need to work on your self-discipline. For example, I like playing Spades now and then, and it's an online game. I'm not going to spend an entire day playing it, but if I set aside 30 minutes for myself, I'll get some rest, take my mind off things, and satisfy that desire.
