I've gone off coffee as of Saturday AM. It was somewhat un-intentional. I just sort of missed my usual afternoon coffee on Saturday, and decided I'd see how long I could go without another cup. It's now Wednesday AM so I'm feeling pretty good about my will-power thus far. Apart from a few head-aches, weird pressure behind my eyes, a few aches and pains and general lethargy it hasn't been too bad. Paracetamol has helped. Keep in mind that I'm going from 3 double-espressos a day to nothing. I fully intend to drink coffee again, I'm just trying to see how long I can hold out (and hopefully be more moderate when I do start drinking it again).
