Congratulations on quitting! It's a very difficult habit to break. As Bob says, the long-term return on that investment in willpower will be significant. As someone who works every day with the tragic consequences of smoking (lung disease, heart disease, cancer, etc.) I often tell patients that the single biggest thing they can do for their long-term good health is quit smoking. I don't think anybody starts life wanting to end it dragging an oxygen tank around with them, and running out of air before they can walk from the bed to the bathroom.
If diving inspired you to do this, hooray for diving!
