I quit over a year ago. Mostly for sleep reasons. I have cheated on my "caffeine fast" quite a bit though. I agree about the duller part, but that should go away eventually. One thing that helped, I used chicory root as a coffee substitute and I found replacing the routine helped fill the void a bit. Also, I was originally hoping I could go back to 1 or 2 cups per week, on an "as needed" basis (i.e. when I needed a productivity boost) without developing a tolerance. The first cup of coffee after a few months off was absolutely magical. But I found that even at 1-2 per week, my tolerance would quickly shoot up. Like you, I used to drink a ton of coffee so I suspect I would need to take a full year or more off with no cheating to really reset the system. A final note, I found that decaf and chocolate both have enough caffeine in them to "muddy" the waters so to speak. To get to a good "baseline" I had to cut both of those out as well.
