I felt like that. I've been purposely limiting my "plugged in" time. I realized most of it was keeping me from doing things I needed to do or really wanted to do. I know this sounds too simple, but I just leave the remote or the computer and do other things. I am, however, using the iPod quite a bit, but it's a tool more than entertainment. It's making me feel less cluttered. I keep lists, such as measurements, reading lists, products, things needed from the grocery store, and study notes. I have access to everything when I'm out. Add Evernote and syncing and it's sublime efficiency. I started to listen to audio downloads. I find this incredibly relaxing.
I don't fully understand Twitter, and I feel that ignorance is bliss in this case. I don't have an issue with text messaging, I only get text messages from my son. I do know that he has issues with the distractions from text messaging because all his friends text often. It would drive me nuts. He said to quit would be social suicide.
The biggest change came when we got rid of cable tv. What an addiction that was. Even though we have a good antennae to capture free tv, and there are viewing options, I find I rarely watch tv now. The husband watches movies on his computer, or occasionally on the tv when it's something we both want to see. I have one favorite show on network tv, once in a while we watch the local news, and the husband watches football. That's it. I'm more active, I read more, and listen to music more often. I'm much happier and content that I'm not being bombarded with advertisements, and junk news.
I should add that these changes weren't easy in the beginning. I was a bit twitchy, and it took a while before the compulsion to grab the remote or computer went away. I still get little pangs, but instead of giving in, I do something else. Now it is time to do something else. :)
