Keep trying, at roughly $5 per pack on a one pack a day habit, you'll have $1800 bucks extra each year to spend on bikes. A much more socially acceptable way to kill yerself!!
Seriously, after smoking hard for 12 years, I quit and never looked back. The craving gets less intense and less prolonged as you go along. Try and pat yourself on the back after each hour then each day, and eventually the days get to be an impressive enough number that would be stupid to jeapordize. I just know that if I took a drag I probably would start up again, so I don't go there.
The good thing is after a bit the smell became objectionable to me, so I don't hang around smokers too much. Hang in there and pat yourself on the back, brother!
Best for the New Year,
Ben
