as they say: Everyone who smokes cigarettes will quit some day.

My Mom quit about 13 and a half years ago, due to large cell lung cancer. (3 packs a day though)

My Dad quit (2 packs a day) within 9 months of her death, cold turkey, and still has not smoked again.
He says it was hands-down the most difficult thing he's ever done in his life, that there were some
days that all he did that day was 'not' smoke a cig.... He says every once in a while he'll catch a whiff
and want a puff, but he's come too far now and he truly does hate the smell, on his clothes etc....
My Dad is 67, and is pretty active now. He rides his bike, walks, and bowls on a team in a league.
I'm glad my Dad is still around, and I miss my Mom every day.

As other have said, quit for yourself, not for anyone else. All of the good aspects of
not smoking will become more apparent day by day. Good Luck in your quest of quitting..!!
