I quit caffeine in January and it took me about the same - 6 months for the fatigue to go away - though I would say it gets much easier after 3 months. I think gradual decrease would make it easier but it would take longer. You might need to step down to one cup of coffee/tea a day for 6 months before quitting. I ended up mixing small amounts of instant coffee with decaf instant coffee so that at the end of the day it was like I had only consumed one cup of coffee. I only did that for a few weeks and then just quit altogether and still got huge fatigue. I have recently started going for runs almost every day and that has helped me a lot so you may be in a better position if you exercise. I tried lifting weights for ages but couldn't get into it then I switched to running and found that to be way better at reducing fatigue for me.
