Hey Cradhika, it has been a long time for me come on ask now, but now, i am here.
And, why you want to get rid of internet addiction? It is good, till you use it for good means. If you are using internet 4-5-6 hours a day for educational purposes, research purposes or to find solution of some problems and some ( not much ) entertainment, it is a good thing. It is ultimate source of knowledge, an endless ocean of knowledge. If you know, how to swim through it, and use your mind in right way, you would have fun and learn, otherwise would sink. Internet is bad only then when you start wasting time here in unwanted stuff, like adult contents, youtube or other useless materials or on social networking sites. Social networking sites are also good, but in a limit, communicating with family, friends, and expressing our views. Blogging, is a very good feature too. Lot to learn there.

What did you used to do before you go a computer? Try to do some of the other things you enjoyed in the past or else try and find new hobbies. Just keep your self busy and try not to think about the internet. You could play an instrument, read a book, watch a movie, go for a walk, spend time with friends and family etc. After a while of not being on the internet you won't miss it as much and probably start to enjoy your life a lot more not getting involved with all the internet drama.
