I'm similar. I drink coffee because I really like drinking coffee. That it's healthy is another bonus point, but at the same time I have to limit myself because the voice in my head says "don't drink too much otherwise your off-days will be harder". Though I am still at maximum 1 cup per day and have absolutely no problem skipping a few days here and there. Good thing about caffeine is that it's very fast to reset back to 0. Other caffeine sources I enjoy as well but try to stay away as much as possible and only consume very very very occasionally. Studies that link telomere length to caffeine (from non-coffee sources) are enough to make me not want to drink energy drinks at all despite me really liking the taste and boost.
