Before the grumpy start making noise, yes, I absolutely am addicted. If I miss two days, then I get a headache for three days. Still definitely worth it. Everybody should drink coffee. There is no good reason not to.
They absolutely shouldn't. Many people suffer negative side effects from consuming coffee even if they don't realize it, like anxiety and jitters. Consuming stimulants is also a bad idea if you already have high blood pressure or heart rate.
> The analysis found that participants with severe hypertension who drank two or more cups of coffee each day doubled their risk of dying from cardiovascular disease, compared to those who didn't drink coffee. Drinking just one cup of coffee or any amount of green tea – regardless of blood pressure level – did not raise the risk, the study showed.

The more general inference everybody with any high blood pressure or health risk should avoid coffee is not supported by the bulk of epidemiological evidence: moderate coffee use appears at worst neutral for many people, possibly beneficial for some.
A comprehensive meta-analysis of decades' worth of cohort studies concluded that moderate coffee consumption (roughly 2-5 cups/day) was associated with a lower or neutral risk of cardiovascular disease overall (coronary heart disease, stroke, heart failure, CVD mortality) compared to no coffee.

So drink up! Drink all the coffees! Unless you are a reply-guy with severe heart problems and an uncontrollable compulsion to drink mass quantities, then talk to a doctor first.
Also don't drink coffee if you don't like it, or you're a Mormon, a strict Seventh-day Adventist, a member of certain Pentecostal or Anabaptist groups, a Theravāda Buddhist monk, a strict Salafist, or part of a strict Ital-observant Rastafarian community. If in doubt, speak to your bishop, branch president, pastor, priest, imam, monk, or whoever guides your spiritual tradition.
In fact, so few spiritual traditions do forbid it, including the most forbidding and censorious, that it may well be considered miraculous. In my personal religion it is tantamount to a sacrament ;)
