I'm sure we've all seen plenty of these articles before, but I find it helps to strengthen my quit even further when I re-read things like this now and then.
Any other tips to add from our long-term quitters?
I think an obvious one that we can all agree with is using a group/forum and sticking with it even after you feel you've been successful in a quit. There are still plenty of times when I feel I benefit from reading posts and threads on here and I expect that will remain the same in years to come (sorry, looks like I'm here to stay :p)!!
