Of all the magical things that we think cigarettes do, curing boredom is probably the most ridiculous. I don't mean to offend, I thought the same way for 18 years. But really, unless you chain smoke, how much of your time would smoking actually occupy? Out of an hour, even if you spent 15 minutes smoking, you'd still be bored the other 45 minutes. I think if you smoked you'd realize shortly after you were done that you'd be just as bored as you were before you lit up. Only now you'd be in worse shape physically and you'd smell like an ashtray. Unfortunately, smoking doesn't relieve boredom. It never has and never will. Take this time to explore a hobby, learn something new; read, write, call an old friend. The best part of quitting is that you start filling your mind and time with things that really have meaning instead of hiding behind a smokescreen, literally.
Good luck.
