Yaw question

All the text books I read tell me that the predominant secondary effect of roll is yaw IN THE SAME DIRECTION OF BANK. They mention adverse yaw as an initial secondary effect, but emphasise that the adverse yaw is nowhere near as strong as the tendency to slip then yaw towards the lower wing.
My question is this: In every aircraft I have flown, the need to hold same side rudder to combat adverse yaw is obvious and very noticeable, yet I have never needed OPPOSITE rudder whilst turning. If the slip then yaw issue was so prevalent, wouldn't we all need to be turning with opposite rudder held on all the time?
Thanks in advance to any aerodynamics afficionados..
