You can only quit if you want too. If you can smoke more cigs before you give up you don't truly want too.
I went into hospital 12 years ago for an unrelated matter but I was on a ward with guys who were all under 60 and with smoking related conditions, some terminal. I'd smoked 20 strong cigs a day for 20+ years then. I now haven't smoked for 12 years and haven't even craved one for 11 years and 10 months. I just stopped that day in hospital and never looked back.
My wife quit after a similar time smoking 20 per day 5 years ago. She used patches for two weeks and hasn't smoked since.
We also both quit drinking for various reasons 12 and 5 years ago.
I will repeat point one, you can only quit for you, not the doc, or wife, but because you want too. At that point you should never have another single cig. But to avoid the huge void you will feel, find other things to fill you time as smoking is 90% habit and 10% chemical. People sometimes say the opposite but it's easier to explain failure if you can blame a chemical rather than strength of mind.
On the plus side, we now own about £20,000 worth of camera gear and a static caravan, all paid for outright with cash we saved from our old habits!!
