Think of all that extra gas you can buy now! Seriously, I commend you on quitting. As a respiratory therapist I can give you all the medical reasons why people should quit but it still boils down to the desire to quit first.
No on ever looks back on their life when they are on their deathbed and say" you know I wished I would of smoked more" but there are plenty I have been at their deathbed that said" I should of quit back when the doctor told me to and I would have another 20 years to spend with my family"
Remember, one day at a time
