Thank goodness that coffee is something I actually like. I stick to no more than 4 cups a day, 5 cups if I'm feeling lucky. And by a cup, I mean an 8 oz cup (a 20oz to me is 2.5 cups of coffee).

When I was in college I was admitted to the ER for arrythmia. The condition was exacerbated by excess caffeine. I went from a pot of coffee a day to 3 cups a day for years, this included exercise and meditation. I refuse to touch energy drinks; while it gives me a shot of energy, prolonged use has consequences like my visit to the ER due to excessive coffee intake. I'd rather focus on getting the correct amount of sleep and taking regular breaks to recoup my energy rather than relying on coffee to feel awake.
