I know you don’t want to internet but when you get back online please see a video called “addiction” by “In a nutshell” on Youtube. I think Internet addiction fits that very well too.
I see so many posts here that are about fighting internet addiction, by blocking sites, disconnecting wifi, etc.. yet, so many people miss the point.
Before you start rehab, first understand why you were so addicted in the first place. What other things are in your life that give you happiness? Do you have a passion project, a g/f or spouse, good friends/family?
It’s very difficult to be addicted to something like Facebook, or Twitter when you have more gratifying things in your life.
