I am at day 9 and it definitely sucks. I have been really lucky and haven't experienced the heavy withdrawal symptoms that some on here have, little dizzy and foggy for a couple of days but it has eased off. I started taking a stress b complex, dopa mucuna, and St Johns Wort a couple of days before my quit and I think they have helped a lot. That may be all in my head but I'll take all the help I can get.
Smokey Mountain Herbal snuff, and Teaza pouches have helped with the cravings.
Stay strong and stay quit.
