I'm a 27 year dipper, first started in college. Light use in the beginning, continued off and on after college, quit altogether about 15 years ago. That lasted 2 years, one little hiccup on a golf trip and I was back on board.
Have quit twice more for 6+ months or so. Always seem to come back.
I believe now I am dipping more that at anytime in my life....for no apparent reason, as far as I can tell, and I know it's time to quit. I'm a 2-3 can a week Timberwolf dark blue, and I really don't enjoy it at all anymore. When I did it less often, I actually enjoyed it some. Now, I recognize it as the parasite that it is, and am determined not to let it continue to dominate the remainder of my life.
I'm on day 3 of my most recent, and permanant, quit.
