Thanks worktowin and Chickdip, I really should check on this thread more often. 
Today, 648 days quit is no magic number, it doesn't mark any years or special numbers. But in my case as I was unable to sleep this morning I realized I might want to document this day. Probably the reason I am up so early and couldn't go back to sleep is today is the most major job change for me in over 20 years. Slightly over 20 years ago I went to work in a factory making construction equipment. There over half the employees either smoked or dipped. Then about ten years ago they banned smoking inside. About 5 years ago they banned tobacco use on the premise. Then 2 years ago they added a $100 surcharge onto health insurance for tobacco use. Still many people on the floor did not stop dipping or smoking they were just a lot more sneaky about it. Still a few people have been terminated for smoking on the property. 
But starting today I am beginning a new challenge with a new job in a different department. I am so glad I have already quit because this would be even more challenging if I had not. As of today I go to work for quality control and am no longer on the shop floor all day. I would no longer have a tractor to duck behind to slide in a dip. Instead I would have to duck in my cubicle and hope no one walked by. Or go to the bathroom and dip in the stall. It would be so much more risky. The offices used to have a lot of lenience because the plant manager was a smoker. Now though the plant manager is a strict non smoker and there is no lenience. Nobody was terminated for smoking on the premises until he came. I am thankful that I quit 648 days ago and don't have to learn a new job with nic rage involved. Almost everyone on the shop floor has a goal of ending up somewhere like Quality Control some day. But many of them don't dare actually do it because they know what would happen if they got caught using tobacco in the offices.
