Lucky, Welcome to the site and on thing is certain, you know that you need to quit. Great intro, thanks for sharing and you'll find that your story is like many of ours here.
We all appreciate the questions you have about what it'll be like during the quit but the answers will not change that certainty. You have to quit. And, it needs to be for you. Not your wife and kids, not because of work nor your Customers. We stress this here because there are many more failed cases than successes when folks attempt a quit for other reasons than themselves. You talk of anger and the anger you should have should be directed at nicotine and chew and what it has done to you during your recent lifetime.
It appears to me that you want to and are ready to quit with the right support. Well, you've found the right support in the site here. I, like so many of the vets here will attest, needed the support of this site to navigate successfully through the first few days of my quit. Past that now and will need the help of the big family here to make the next milestone. One day at a time.
Specifically addressing the questions you had: Q) If I can suffer through the initial shock of being tobacco free, will my anger subside? Or will I be more inclined to be hot headed and bitter from my quit date on out? In other words, will I be able to be the way I am today where my addiction keeps my anger at bay? A) As stated by King Nothing above, all of our experiences are different. What we can say is that you are likely to experience some anger, hot headedness, as you make through the initial three days of the physical nicotine withdrawal and some lighter, long term issues as well. Its how we all manage it that makes the difference. Again, as mentioned, you have us here for that. Reach out here to vent, piss, moan, etc. We've been there and get it. Folks are available here on the boards and will also share phone numbers with you so that we all have a net! As you make your way around the site here and read veteran accounts of their quit, you'll learn methods and have tools to handle the anger and frustration that we all go through.
Question regarding cold turkey. It's the only way to do it and the only way we do it here. We are addicted to nicotine and must not use nicotine. That's right, period. At the start, we were all some sort of mess and made it with the support of the family here. That said, if it made sense for you to take a few days off of work to mitigate a bad situation as you fought through the first couple of days of the physical withdrawal, do it. A couple days off of work is a small price to pay to living your life free of nicotine and all the goodness that comes with it. Again, if things are getting funky with you and your gonna lash out at folks, come here and lash out, rant here with us. We'll need your help pat some point too!
We'll help with the commitment to the quit. We post roll every day, early in the day, stating that we will not use nicotine today. Its that easy. And you got it, its that hard too. That's why we are all here quitting together.
I am thinking we've addressed your questions regarding the anger and bitterness we have all experienced and shared some examples of how it can be dealt with.
Come join us and quit. The time is now. It's not a pipedream to be quit today. Quit with us one day at a time, every damned day!
