First off, you are in for a wild ride. Ben if this is what you want it will happen but its going to take some work. I have pretty much been awol for a few months. I actually came back in here today because I was dinking around on my phone at work and opened up "My Quit Tracker". It is for Iphone and Android. I am at 249 days. It worked for me as a great motivator, and on days like today when I am stuck in a chair and not out in the field I can look at it to remind myself why I am not chewing like the guy sitting next to me.
Get the app, get seeds, jolly ranchers, fake snuff (the smokey mountain was a god send, the stuff is so nasty that after a while you can't imagine stuffing your face full of it). Get your favorite soda pop, energy bars, ice cream. What ever it is. You can deal with getting off that stuff later, you are in it to fight this one demon right now.
I chewed for 5 years, and was up to 2 cans a day at my worst. I was a few attempts into quiting when I finally dedicated and got on this site. The biggest thing is the prep. If you are not prepped both mentally, emotionally and physically (all that substitute stuff makes it easier) it won't happen.
