An option for quitting/cutting down that I don't see mentioned often is using low-caf coffee rather than having to go for cold turkey or "quantum leap" full-caff to decaf cups in the same day. Perhaps it's so obvious that people don't think of it, but you can just mix your normal coffee and decaf in the same drink to get the dilution you require. I have decaf and normal coffee beans, grind them and store them in separate bags and just gradually decrease the caffeine dosage through the day, and the daily dosage through a longer period if I'm trying to cut down. FWIW
