According to WebMD, people in the United States drink more than 600 million cups of coffee every day. There are many health benefits from coffee, including reducing your risk of cancer, stroke, Parkinson's, dementia, and Alzheimer's. Typically, four cups of coffee can be safe, but more than that can have adverse effects, from increased anxiety to insomnia. On the other hand, you can have too much of a good thing.

A typical cup of coffee contains 80 to 100 milligrams of caffeine, and don't forget decaf also contains a bit of caffeine — about two to 15 milligrams per cup. While 400 milligrams of caffeine — or four cups of coffee — is the maximum you should have a day, that can vary per person. Some people are more sensitive to caffeine and should have less. Finding how much coffee you should have in a day can be a trial and error process. If you experience symptoms of overuse of caffeine, like the jitters, cut down on the coffee (via the FDA).
