Smoking
Smoked for about 35 years a pack a day quit pretty much cold turkey with help from a generic drug Wellbutrin 15 years ago. I have always felt like an ex smoker is like an ex alcoholic it don't take much to slip back into that pack a day routine.
Good luck to ya and to anyone else out there doing or thinking about quitting. Don't kid yourself, it is hard but doable.
Was in the gift store in a hotel in Honolulu, HI buying a coke and a guy asked the clerk the price of a pack of Newports, mind you this is a pack cause they don't sell cartons, a single pack price here is $13.10 a flipping pack. At that rate you will have some serious bucks for your ride.
Go for it.
