I was addicted to coffee, but couldn't see it or would deny it or that it mattered. I could see it in other people, and I don't just mean the people that make facetious remarks about their ravenous need for coffee. I saw it in people's behavior. I recognized some of those same behaviors in myself. So I quit. The actual caffeine withdrawals take only a couple days to overcome, and I had been through that many times before when I quit only incidentally. I haven't had coffee or significant amounts of caffeine in more than 7 years. My health and BP have always been excellent and low, so I'm not making any claims about that. I will say that I feel mentally better without caffeine.
