Mutley , you've come to the right place. Congrats on the grandfather!
Read the intro to new quitters, find your quit group (hint you will be at 100 days quit in November, so go to the November 2015 quit group, read, post roll, and trade contact info for backup to help eachother through this). Mutual accountability is the key, a group to text or call when 6 months from now another smoke shows up.. To get you past the crave and temptation.
I'm probably a generation older than you, but just as stubborn and just as much an addict. This can work, with the accountability and help of other bad ass quitters.
I quit with you today, and every damn day in front of us.
