John,
A little late welcoming you here....I can hardly believe they're already working on a JANUARY class....wow.
I know your struggles all too well. With the exception of a 14 month stoppage back in the early-mid 90's, Copenhagen ruled my life for nearly four decades. Even AFTER the physical withdrawals are over, your brain is having to rewire itself to shut down all the nicotine receptors it built up over all those years of dipping. They are the little monsters inside your brain housing group that make you feel like you're losing it. If you don't remember anything else, remember this....NO ONE ever DIED from nicotine withdrawal. It may feel like it at times but that's just another lie nicotine uses to try and pull you back in.
Keep at it....as many have said here; it'll suck until it doesn't. My experience is that some days (some hours) suck more than others but over time the ratio of sucky to okay improves. Glad you're here and doing the hard work and heavy lifting that is being quit. One day at a time. Or, as I "stole" from a Terminix commercial...."Not Here, Not Now, Not in My Lip". NHNNNIML!
R,
JDW
