I've chewed cope and grizz wintergreen since I was 17 and I'm 33 now.
Quit on Monday 6/26 at around 9 AM. Made it through 6 hours of poker Monday night by chomping nicotine gum.
So far so good.
I work shift work in an industrial environment where dip is common and accepted. My first day back is tomorrow. It's going to be tough, but I got it. Going to continue to use nic gum as a crutch as well as seeds and regular gum.
