Haha, my longest session was 12 hours of non-stop runescape experience. I remember that day I was trying to finish Recipe for Disaster and I was having a sudden urge for the barrows glove. 7 days later, I got hacked around 67 mil and the only thing remaining on my player were the gloves :_). You should definitely start thinking about getting some sun and sleep. You're just abusing it hehe, best of luck!
