Forest,
You can do this. Read everything you can. Click on the Killthecan.org link above and read the Tom and Jenny Kern story. When I needed motivation to stay quit, I pulled this site up on my phone and read their story. The part where his daughters were pleading "please daddy don't go" as he took his last breath...that was more than enough to remind me I was sick of nicotine.
You'll have physical withdrawals early on. Turn the tables on the Nic Bithc. Learn to enjoy them. The Fog is a privilege that badass quitters GET to go through. Withdrawals are the feeling of earning your freedom.
I don't have any tricks or shortcuts for you. Everybody must go through this in order to be quit. But you're in the right place, brother. Every last person here has been, or is going through, what you're feeling right now. YOU CAN DO THIS!!!
