Today should be day 3 for you, that's bad ass. These days are not easy to come by. As fo your original question, is there any best method to quitting, or just do it?:
You're in luck! There is a best method.it has worked for me everyday since May 12, 2014. It isn't however a magic pill that you and I were hoping we'd find when we googled some variant of "how to quit dipping." this method i speak of quitting one day at a time. It's accomplished by giving your word and being held accountable to that word. Every single one of us here are nicotine addicts, just like you. What better a place to hold you accountable than a place with hundreds and thousands of nicotine addicts?
The first step in this process however is on you. You must give your word by posting roll. That's your word as a man, given to your brothers in February 2016 quit group, that you will not use nicotine today. you can keep your word for 1 day right? There will be a good number of supporters who post their promise with you as well, to let you know that it is possible and you are not alone in this fight.
I see you posted roll on day 1 a couple days ago, but haven't posted roll since. Well if you are ready for freedom and put any value in your word, this method will lead you to freedom from nicotine. Next step is up to you, it's our job to show you the path, you've gotta be the one who walks it.
Regarding your oral fixation question, there are a number of ways to help tackle craves. These are fake, seeds, gum, beef jerky, hard candy (fireballs). Many people use some or all of these tools while walking the aforementioned path, some don't. I used fake dip (hooch spitfire was my favorite, grinds was decent, Smokey Mountain is probably 2nd most popular) and beef jerky pretty heavy early on. Eventually I just kind of stopped using it except rare occassions and now I havent bothered looking for the couple of cans i know are laying around in 6+ months. I still chew seeds at baseball games sometimes. Some quitters are in the camp that they want to simultaneously break the habit of stuffing chopped brown plants in their mouth, addictive and cancerous, or not. My suggestion is it doesnt hurt to try, but the important thing is getting on roll and taking charge of your quit every day.
