Oh my... why to quit? I smoked on and off for a number of years. Last Thursday, I was diagnosed with emphysema. There's no cure, and it continues to get worse. Without health insurance I would now be taking about $700 worth of medications per month (as it is its only $100 or so). I get winded going up stairs, not much of a cough, yet.

Since there's too much snow and ice for my liking, I don't know how it will effect my biking, but it won't help.

I quit smoking 5 years ago, but that was way too late, it seems.

How I quit (hope it may help someone).

Step 1 (the most important): Decide you are going to quit, forever, and never smoke again. Get it firm in your head. Accept that you won't ever enjoy that addictive little smoking stick.
Step 2: Pick a day. I chose a Saturday of Labor Day weekend - a 3 day weekend for me. Buy some nicotine gum if you think you'll need it.
Step 3: The night before, before you go to sleep, dump any remaining cigarettes down the toilet.
Step 4: Day one - Remind yourself of step 1. Do your normal routine - coffee, breakfast, etc. Just don't smoke. It won't be fun or easy. Try the gum whenever there's a real urge for the nicotine buzz.
Step 5: When I really, REALLY wanted a smoke, I got on my bike and rode a LONG ride. Beat myself up. Got home, drank enough water to not be thirsty then went to bed for a nap.
Step 6: Sat, Sun and Mon - repeat step 5. Keep drinking plenty of water - it helps to detoxify. Don't cheat. Every moment you don't smoke is another moment deposited in your non-smoking life.
Step 7: If you make it to Monday morning, congratulate yourself. Damn fine work. If you go to work, tell your co-workers you quit. Bask in their praise.

Each successive day is easier. You will think about smoking lots, but remind yourself of step 1. You're a former smoker.
