Over 15 years for me now. Exercising, including just getting out for a walk, does help. Treating myself to my first post-college bike was a big inspiration and the start of where I am today. Also, when I was trying to quit, a neighbor who was a nurse said: "I have one word for you. Toothpicks." By golly, it did help. They help both with the fidgety fingers and the oral fixation issues. To this day, I still keep toothpicks around. Of course, the first month of my stop smoking effort the inside of my mouth was almost shredded from my fidgety, nervous chewing the toothpicks into tiny bits
but that too passed. Also, don't beat yourself up if at first you do not totally succeed. It took three solid efforts on my part to finally quit. Having the desire and will to quit will get you there!
