It's been over a year now, and I can't imagine going back. The only trigger I have is seeing someone else smoke, and even then it has never been more than a fleeting thought that dissipates within seconds. I know exactly what 2-3 puffs would do to me, and I have no interest in going back. I've never had the urge to buy a pack myself or to bum off someone. Smoking is now well into my past, and for that I am thankful.
I got the well-known "nightmares" from Verenecline, but I actually really enjoyed them. Those dreams were some of the most vivid and intense I've ever had the joy to experience. In fact, I still have the last 50 1mg pills leftover that I didn't need to use, and I've only kept them because I know I'll eventually use them just to revisit that kind of dream state. :)
