You are in for a shit storm of misery for a few days, maybe even a few weeks. Go and post roll in your group. Promise not to use nicotine for the day. Then wake up and make the same promise tomorrow. If you can do that, you can quit. If you can't, you will cave.
There is no luck with this decision. You either make your commitment, or you let the nic bitch back in your life. I've been clean 56 days now because of this site. You can do it, but you have to commit.
