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

Yes, drinking too much caffeine can have negative effects on your health. Caffeine is a stimulant and too much of it can cause anxiety, insomnia, headaches, high blood pressure, heart palpitations, and even tremors. It's important to monitor the amount of caffeine you consume and limit your intake to no more than 400 milligrams per day.
