Is there such thing as too much coffee?

[CaffeineFx]

Yes there is a limit as to how much. It depends on the person, the activity they are performing, and tolerance. A good rule of thumb is to always stay below 400mg of caffeine a day, and make sure to stop consumption after 2:00pm so that your body has time to break down the caffeine before bed.
