I've gotten off of coffee a few times in my life and have found this to be the best way to get off without suffering the headaches.

Buy a pound of decaff and half a pound of regular.

Mix half a pound of each. When you get half way through the mix....add another quarter pound of decaff. Once again.....when you get half way through the mix....add in the last quarter pound of decaff. When it's all gone, if you still want to enjoy the taste of coffee...you will be able to drink plain old decaff.

I'd given up coffee pretty much completely since starting Atkins last September, but on occasion....often for social reasons, I do enjoy a decaff at Starbuck. My experience has been that they have the most flavourful decaff in the marketplace.
