I gave it up.
Bought something called Dandy Blend (dandelion, chicory mix), supposed to help with the caffeine withdrawal (I really didn't have any, a couple of mild headaches) and I actually like it better. Doesn't really taste like coffee...kind of of like hot chocolate, coffee combined...different, but good. I use a spoonful of choc creamer (no sugar) in it and that's all...hooked on the stuff.
