Hey brother and welcome! Don't worry about the Chantix. You are in what is called the fog. Don't worry, it will pass. We have all gone through it. Stay on this site, get connected w/ your quit team and the rest of us, post roll, drink lots of fluids, stay off the chew....stay off the chew...fuck, something else....oh, yeah, stay off the fucking chew.
Look at the "fake" dips such as Smokey Mountain. Smokey Mountain to me is fucking nasty, but there is another product (there are many others) called Hooch. To me, Hooch is AMAZING!!!!! Some people agree and some don't. I think all the herbal dips out there suck a huge one, but Hooch IMO is the best one out there. The only shit thing about it is mail order but it takes no time to get to your door step.
You are making a great decision and for that i'm very proud of you. We don't talk quitting for eternity here, we talk about day-by-day. This is why posting roll is so important. You are making an oath not only to yourself, but to the rest of us that you will remain nicotine-free for that day. Then for tomorrow and subsequent, you do the exact same thing.
