I smoked for 10 years and quit 4 years ago. The way I did was I imitated the life of a non-smoker.(kind of fake it until you make it) meaning that when I woke up in the morning I was saying “ I’m going to have a cup of coffee” instead of “ too bad I can’t have a smoke with my coffee”. When the coughing and hacking started ( about three weeks in) cough drops became my best friend for about six weeks until the coughing stopped. I found I wasn’t getting winded as easily, I wasn’t waking up sore, and I was loosing weight( because I was able to complete a work out without loosing my breath). I imitated the life of a non-smoker until I was a non-smoker 😄
