My reason for wanting to quit caffeine was related to willpower and self-control. I wanted a stronger mind-body connection where I'd readily act on my desires rather than delegating to "I'll do that once I feel properly caffeinated." I was finding that I wasn't doing much with myself after work hours because my energy levels felt low once caffeine wore off and because I wasn't training myself to be comfortable doing things even when I didn't "feel" like doing them. Those behaviors made me uncomfortable with myself, but I never felt like I had the time to address them while working a full-time job. At best, I'd get two day "detoxes" over the weekend and then hop right back on the bean juice Monday morning.
