I had a big RS problem a couple of years back... I'd played it in my youth (I would've been... eight? Maybe nine?), and revisited it out of 'nostalgia' shortly after I finished my A-Levels. In my third year of Uni I had a nightmare about no longer being ranked for my Fletching skill, and realised it was probably time to kick the habit.
Now three years clean, by which I mean "I find other ways to waste my time on the Internet".
