Congratulations on a fine decision. I can vouch for redtrain about hunting. I get all my critters with a toothpick in my mouth now, and it's even more rewarding.
Remember that this quit has to be for YOU above everything else. If it's based solely on your family, you might use them as an excuse to fail or fail to get back at them for something. As odd as it may sound, that's the standard functioning of the addict mind. I think you've got your heart in the right place.
Stay focused on your quit, absorb everything here, and take it one day at a time. As the days rack up, you might even get to be there when your great grandson takes his first. The possibilities are endless without a lip full of death. Welcome aboard, buddy.
