I never stopped drinking it but made sure I only had one good real coffee a day. First thing in the morning I swapped to tea and then had my coffee when I got to work. Morning tea I would do a Green tea with Jasmine and then in the afternoon a hot chocolate. I hate decaf but I like the idea of half normal/half decaf to get used to the idea if you are finding cutting down difficult.

As others have mentioned at around 6 weeks you might find that you lose the taste for coffee anyway.
