I don't consider myself an addict. The internet is just the way I keep informed be it news, forums, shopping, entertainment...etc.
I got rid of cable AND t.v. a little over 3 years ago.
Got tired of running around town shopping for something I wanted only to find whatever I wanted was rarely in stock (thus my mostly shopping online --- except groceries).
The internet is my entertainment (Netflix, YouTube, etc...). It's my vessel for keeping informed from several news sources (local, national, international) .... It's where I can by things I want/need and have them delivered to my door (convenience)...
...It can be somewhat overwhelming if I let it ... but I believe I'm disciplined in that it's not something that I have withdrawl pangs if I go without. It isn't my life ... but it does play a big part of it. I know I won't die if it was suddenly gone.
...to me, the internet is much more than sitting in front of a t.v. half the day ... 50+ channels ...
The internet is fascinating ... but I know it can be dangerous in a sense because of social media ... information overload ... fake news - real news reported as fake - fake news reported as real ... good lord it can be overwhelming.
I enjoy my time online most of the time. I prefer it over cable t.v.
