Does your body ever stop responding to creatine over time?

Some people worry that creatine "wears off" after using it for years because they stop noticing any obvious effects.

But once muscle creatine stores are saturated, the goal is simply to maintain those levels. Not feeling something doesn't necessarily mean it has stopped working.

Have you been taking creatine long term? If so, do you feel it became less noticeable over time, or has your experience stayed the same?
