I'm not sure that's the best idea. The key is to quit, but on a boring note - if you have a great time with friend PKing or something then quit the next day, you'll keep thinking of how fun it is and how much you want to do that again. If you do something really boring, say, grind fletching for 10 hours, waste the day, feel like you didn't accomplish anything, and THEN quit, you won't even miss the game. Its not the smartest move or easy for that matter to quit an addiction all at once. Try to reduce your time a bit each day.
