Regular coffee, though extremely popular, has its down sides. Unfortunately lots of people and scientific research prefer to focus on the pros of coffee. For people who for example need to be careful with dealing with stimuli, it makes sense to drink something else than coffee. A search engine search for caffeine stress mental health may bring about some less known information about this. And I know from experience that once you're completely off regular coffee life is different. It may take a few weeks for that.
