I've been smoke free since May 13th. Within 5 days that dreaded morning cough was pretty much gone. As I sit here (at work) a co-worker of mine (who smokes) keeps holding back coughing. It's like she is constantly sputtering. You know - kind of like a car which is misfiring. Eventually she'll let out her smoker's cough. I remember when I too was like her. It is so nice to not cough all the time. I LOVE vaping!!!
