Can a human drink too much coffee?

    Yes, a human can drink or eat too much of anything, which is why people use the phrase “everything in moderation”.   Some common side effects of too much caffeine can include dizziness, headache, irritability, nausea, nervousness and more.  Stick to 3 or less cups of coffee a day.

    More than 500 to 600 mg of caffeine daily (the equivalent of four cups) can cause adverse side effects such as insomnia, nervousness, and nausea. Caffeine is particularly harmful when mixed with certain antibiotics, such as Cipro or Noroxin, and the herbal supplement echinacea.

    Yes. Kristen and Valkyrie are correct. I suppose it mainly has to do with the caffeine. In other words, “Too much” decaffeinated coffee may be a significantly larger amount than “Too much” caffeinated coffee.

    Yes. In addition to a caffeine overdose, as other users have mentioned, too much coffee in the long-term can also lead to adverse health effects. Drinking too much coffee can raise your blood pressure, increase the chance of an ulcer, and prevent you from drinking enough water, which is unhealthy. Though people are accustomed to different amounts of caffeine per day, ideally, you should have no more than 200 or 300 milligrams a day (about 2 cups).
