I've heard that if I drink too much coffee, it could be bad for my health. Is this true?

Yes, it is true. Drinking too much caffeine can have negative effects on your health. It can cause headaches, anxiety, insomnia and stomach problems. You should limit your caffeine intake to 200-300 milligrams per day, which is about the amount in two 8 ounce cups of brewed coffee.
