Well. I can tell you this...
First don't worry about craving something that "will never be again". That tells me you aren't thinking about TODAY, you are thinking about forever. The concept of "forever" is a tough one to grasp, not just for quittin nicotine, but for anything. We are only immortal for a limited time, my man. Stay in the here and now. I know it sounds easier than it is, because I too struggled with the very same thing, but it's funny how different your outlook is day to day.
I had many dark days in my early quit. Couldn't grasp the concept of one day at a time, did not think things would get better, and was just kind of "floating", unable to see the forest through the trees.
However I had something you seem to have as well.
Resolve.
I knew I was and still am doing right. I believe you do too.
The good lord gave me a moral compass to steer by when I came into this world. I let nicotine fuck it up and take me off course. Not that I was some slovenly degenerate, but I was letting addiction run my life. I was on a path not only to short change my own life, but my loved ones as well. My wife, my kids, my parents, friends, and family...they were all going to suffer because of my addiction.
I've had loved ones take early thanks to the perils of nicotine, and from reading your intro thread, so have you.
It sucks and it's selfish behavior that caused it. Tell me every time you filled your lip you didn't have some thought of "I know this shit can kill me but...fuck it". I know I did.
Time to take that compass back and return to the proper path. Will it be easy to get back on track? Fuck no. Will it get easier? Fuck yes. Will it always be worth it? You bet your fucking ass.
I'm 470 days quit, cold fucking turkey, jack. Hardest thing I've ever done in my life, yet also the most rewarding. Whenever anybody asks how I did it, I tell them, "the same way I'm still doing it...one day at a time".
Don't try to eat this quit in one big bite, it's too big, you might choke. Grab some KTC silverware and cut it up into bite sized pieces. That's how you take this shit down. You need help cutting your meat, you got a ton of people here willing to help you
Quit on....
