How can I stop being addicted to social media?

I constantly find myself being engulfed in social media (Fluther is no exception). The time I used to spend doing studies, reading books, listening to interesting music is now spent on Facebook, talking to people through IM services and Twittering the hell out of my life.

How can I be constructive and let go of these things. Sometimes I find myself utterly bored but I just can’t think of anything to solve the issue. I just autopilot on facebook.com and sometimes realize I’ve been looking at photos of people I don’t even know for like 30 minutes.

I don’t want this to change me into a sloth, what should I do? At my work I’ve decided to block Facebook.com and reddit.com because they seem to consume most of my time but I still want to be able to keep in contact with all the people there so easily.

I’m very easily hypnotized by stuff like that. That’s one of the reasons I don’t watch TV anymore. Facebook however is more difficult.

Any advice? I think a lot of people could learn something from this discussion.
