How long is too long to be on Glucophage/Metformin?

Been on for few years now. Started with only 1 500mg tab after workout with couple 50/50 protein/carb shakes 2hrs apart. Then started taking on weekends upon awakening with same protocol. Then 2-3 tbs with large pie. Since been doin this for few years now any chance I may be permanently dependent now?
