There will always be stores where you can buy cigarettes.
There will always be people who smoke.
There will always be alcohol to loosen you up.
So, why worry about quitting? You aren't giving up anything! You will miss doing it because you've done it for so long and it's such a huge controlling part of your life but why worry about it!
You can go back anytime you choose to. (once you taste a glimmer of freedom, I doubt you will ever see smoking as something positive again.)
After smoking for 40 years, it's been my personal choice not to.
It can be your choice too!
