How much is too much coffee? I drink about 5 cups a day.

Hello Joann,

The Mayo Clinic states that for most healthy adults, drinking two to four cups of brewed coffee each day is not harmful. But, drinking four or more cups a day can cause insomnia, nervousness, restlessness, irritability, stomach upset, fast heart rate, and muscle tremors.

Joann, are you experiencing any of these symptoms? If so, you may want to cut back.

Regards,
Maryann
