The U.S. Food and Drug Administration believes that a healthy adult can consume 400 mg of coffee per day, which is about 2 to 3 cups of coffee , generally without any adverse effects. Of course, this data is not fixed, because everyone's sensitivity to caffeine is different, and the speed at which caffeine is broken down in each person's body is also different. You should define how much coffee you can drink based on your specific situation.

Generally speaking, drinking too much coffee can cause symptoms such as insomnia, anxiety, nausea, irritability, and increased heart rate. Even if these symptoms occur after drinking a small amount of coffee, you should be aware that you have exceeded the limit.
