When I first quit I remember seeing a table of benefits like this and couldn't imagine the long term benefits. I was only really wanting to lose the morning hacking cough. I am still amazed by the body's ability to heal itself from the damage we inflict on it and this should give us all hope. I celebrated by making a pizza with ham, artichokes and mushrooms. I am proud to join the quitters that have reached a decade and would like to see everyone reach this milestone.
