I have been vapeing 3yrs now also and i change flavors every few days just to keep that from happening i use ry4 maybe a week then switch to grape a few days then flue cured then 555 just change it up and i have not had and analog cig for 3yrs now. I think alot of it is just forming a new habit when you first start vapeing.Just dont give in and let yourself smoke a real cig after a while when you start smelling and tasteing things from not smoking your taste will change even more atleast mine did.
