Hey pal, glad you reached out. This is definitely the right place.
I have some good news and bad news. The good news is that you don't have to quit long term, you only have to quit for one day. You quit today, you go to sleep, you wake up tomorrow and you quit for one day again. If you think about it as "forever" you'll never make it. Forever is way too big for anyone to deal it, so just do it one day at a time. Worry about tomorrow as it comes.
The bad news is that you're going to need a better reason than for that job. You can't quit for a job, a girl, a parent, a million dollars. You have to quit for yourself; because you want freedom so badly that it's intolerable to be a slave for one more minute. You have to honestly and personally want it for yourself. That job can be the catalyst, but you're going to have to reflect on what you really want and come to the conclusion that paying a tobacco company to slowly kill you is insane.
It is possible though. There is a clear path to getting there outlined at this site. Buy in, follow the process and you will be successful. Go find the section titled "Quit Groups" then find the "December 2016 Pre-HOF Group" and figure out how to post roll. That is your promise not to use today. Make that promise first thing every single day. It won't be easy, but it will be worth it. It's the price of entry for finding support on this site, you don't get one without the other.
Let me know if I can help.
