Do whatever it takes, but do it NOW! Don't do what I did, i.e., repeated, half-hearted, lame a$$ halfway attempts for about 3 years. After 25+ years of a 1 to 2 pack a day habit, I knew I wanted to quit. I just didn't realize how badly I NEEDED to quit. Then came a major heart attack. Two stents latter, I threw out every cigarette in the house and quit cold turkey. No, it was not fun, but it beat the alternatives.
That was six years and a whole list of lifestyle changes ago, and I'm a much healthier and happier person today. For me, fear was a great motivator. And make no mistake. Smoke and you either die early or end up being some sort of cripple. It's not a matter of "if". It's only a matter of when.
So do it. Do whatever it takes. Do it now, before you've irreparably damaged yourself. Your luck will not last forever, but the consequences of continued tobacco abuse will.
