Oh I don't have any symptoms, yet, just trying to stave it off if and when I develop it! I've heard it can hit even after working with it for years, just trying to be cautious, I work a lot of cedar and want to continue working it!
I have been working with it daily for 10+ years and have not developed anything yet. (Cross my fingers) I think you may have worked it for longer. We are trying to control dust as much as possible nowadays more than we did 10 years ago.
