Yeah, I tried Evony for a while recently, and it has the same effects - it starts to interrupt your sleep because you don't want to risk not being there and someone attacks you. That is when you know you shouldn't be playing it any more. Even then I bizarrely caught myself spending several hours taking down my cities to ensure there was nothing left to steal after I stopped playing (conversely this is a deliberate tactic to use to stop yourself being tempted back so maybe it was a worthwhile investment).
