One thing that worked for me was that I picked a hated exercise to do in lieu of chewing or smoking. I picked pull-ups and push ups. I HATE those! And I couldn't even do ONE pull up when I started. But I just couldn't stop thinking about getting my nic-fix, and I was weak in body and will....I got mad about it. I realized I wasn't in control of my own life.
After awhile, between the anger, stress, tiredness and all the other little perks that go along with quitting nicotine, I actually started to rid my mind of the thought -because every time I'd think about chewing or smoking, I knew it would lead to more painful exercising! LOL!
I never converted into an exercise-addict. Once I rid myself of the urge to chew and smoke, I basically went back to normal life.
But, I bought a new bicycle and I am starting to ride it more and more. If the weather stays nice, I think I could really get into bicycling again. I used to love it as a kid...then forgot about them when cars came along. As long as it remains enjoyable, I could ride this thing a little bit everyday. It's actually really fun! It reminds me of that feeling I used to get when I was a kid -when a bicycle was basically your trusty steed! -much better than the feeling of coughing up lungers first thing in the morning!
I think a key to quitting is finding something that will make you angry enough to fight yourself and beat the sh!t out of yourself...until you win!...And then reward yourself with all the money you'll save....maybe that dream drum kit or old K Zildjian...?
