Cadu, I feel your pain on trying to quit. I quit cold turkey almost seven years ago and ooooh boy do I still miss it! But I love being able to breathe better and not stink
better.
People have given you some great advice about timing and the pros and cons of doing it while you're OP so you've got lots to consider there. I'd just like to add this as another motivational tool for when the time comes.
For me, looking at this chart sometimes got me through some really hard days and helped keep me from falling off the wagon because I knew it was sending me right back to square one. As a result, I haven't had a single drag of a cigarette since I quit June 1, 2005. Hope it's helpful!
What Happens In The Body When
A Person Stops Smoking?
• 20 minutes: Blood pressure drops to normal; pulse rate drops to normal; body temperature of hands and feet increases to normal.
• 8 hours: Carbon-monoxide blood level drops to normal; oxygen blood level increases.
• 24 hours: Chance of heart attack begins to decrease.
• 1 to 3 months: Circulation improves; walking becomes easier; lung functions increase 30%.
• 3 to 9 months: Coughing, sinus, fatigue, and shortness of breath decrease; increased ability to "clean" lungs, reducing likelihood of infection; body's overall energy increases.
• 1 year: Added risk of coronary heart disease is now half that of a smoker.
• 5 years: Lung cancer death rate decreases by half.
• 15 years: You are no more at risk of heart disease than if you never smoked!
