Got the machine just in time for my annual coffee abstinence! For about three weeks in March, I go off coffee (and make some other dietary adjustments as well). I start the wind-down this coming weekend. Used to go "cold turkey" and that is like "Ouch" - guaranteeing a day or two on my back with a shocking head. So an "easy does it" reduction over several days and all is fine. Weak tea for hot drink through this period. Don't worry, I'll be back full of caffeine in late March.
