Over here, in the back (hand waving).
I have quit so many times. Always sure I will not go back.
I used to quit in the spring so that it would not interfere with summer hiking. But each fall I would be teaching a class where coffee was served. It would smell sooo good, my hands would be cold from scraping the snow from my windshield and I would want to just hold a cup, just sniff the aroma (tea and chocolate would never do when the snow was falling.) At first decalf would work fine, then there would be no decalf. I would resist, then have just a sip of a girl friends or my husbands, then a gulp, then I would refuse to return the cup and I'd be hooked again.
It is so hard to get off of so I just quit hiking. Actually I have injuries that keep me off of the trail. Now I kayak and if I am on the water before the sun comes up then a cuppa jo tastes so fine when I put in.
My advice-- stay away from groups that have coffee. Have courage, stand firm.
