I quit about 18 years ago, but I was never a heavy smoker - 10-15 a day, maybe 20 if drinks were involved
This was before the day of the patch, gum, pills etc. - I just had to take it like a man!
I will tell you one thing, you will find nicotine has the strongest urge addiction of ANYTHING else. There are still times when I'm drinking when I crave a cigarette, even after all these years.
But quitting can be done

Get your kids to harrass you about stopping - they're pretty persistent
