Addiction? Yea it does, the name itself says so. It enslaves your brain and its forcing you to think that it is the most important thing:more important than your job, family, friends.
I ususally buy myself a book or a small figurine only because I love them. Sometimes I take a photo and make a collage of my great moments. Hope this helps.
Disconnect and unplug can mean anything you want. I set my phone down before I start reading for the night then check it off in the morning. It can really mean anything you need it to mean.
