nope never go back. Been testing the waters on how I am doing by using the 0mg nic level more and more often as well as leaving my E-cig behind.. Just trying to see if I can let go of the physical habits I developed on analogs. The biggest ping I wish I had something is the drive back home from town.. Getting to town and running around no longer bothers me,, but it's like clock work it's on my mind when I jump in the truck to drive back home... (easily forgotten and I drive home just fine) but it's interesting how some things just trigger the impulse when so many others. So for right now the e cig stays parked at the computer and I've been ok with that...
