I dont smoke...but my father-in-law smoked for 37 years. He smoked a pack a day and has tried to quit but never worked. Well he is VERY competitive, and so I bet him $600 that he couldn't quit for 6 months. Well it's been about 3.5 months for him now smoke free and I really think he is done. Plus being a newlywed, I think he wants to be sure he will be around for a while to see his grandkids....and I will be very happy to fork over the $600 to him in a couple of months...
