Milestones Milestones mark accumulations of smoke-free-days such as one week, 30 days, 180 days, 365 days, etc. Many have Rewards attached to them. Some Milestones have their own Quitticisms (like Tweener, for the 50-day Milestone).
Remember - The urge to smoke will pass whether you smoke or not.
Remember - Smoking actually really honestly does cause death and disease!
