It was really amazing to me. For the first time in 30 years, I was able to do what all the light/non-smokers/non-addicted people did, just quit, without going through the roof. It was amazingly simple.
I have returned to smoking because I enjoy it, not because I need it. I quit again, just to make sure I could do it again, so easily, and it was no problem.
My opinion is that there is some type of chemical imbalance in my body, which smoking and welbutrin balance out. I am much more at ease now too.
