Okay let me get psychological with you. Any addiction is like an illness. Nothing can cure it in a day. Only way to cure and illness is by taking medicine. Your medicine against runescape would not be quiting, because that wont very easily happen. What you need to do is to go out more, get a girlfriend if you dont have one. Now that might have sounded like an insult but its not. When i got a girlfriend i cut down on RS so much, days went past without me even thinking of it. Cutting down will also help. Start playing less and less every week. Soon enough you will have cut your playing time down to 1hour a day, and thats perfectly normal rate. If you really WANT to quit there is always the selution of making the game uninterresting for yourself. dump EVERYTHING you have in your bank. This way you will have nothing. You will have to start over. It will be so boring you WILL quit.
