I smoked for 10 years, anywhere from one to two packs a day and when I quit I felt worse than ever because of all the tar. My tar process lasted about 2 months but I think it took longer than it should have because I quit at a time of year when my allergies go nuts. After it was over it was all worth it though. Congratulations on quitting smoking, with a two pack a day habit you are saving your life and quite a bit of money to boot.
