I am smoking again.  This time I lasted only a week.  At least my wife is understanding.  What broke the camel's back is that I simply couldn't get any work done.  I would sit in front of my computer and my concentration would evaporate with each eyeblink.  So I am smoking again and able to hold a thought for longer than a minute.  As soon as this project is done, I'll try to get back on the wagon again.
