I want to caution everybody out there, if you're somebody who suffers from anxiety or panic attacks, and you're not used to ingesting caffeine and you run out and ingest 400 milligrams of caffeine in the form of espresso or yerba mate or an energy drink or in pill form, that is going to be very uncomfortable for you, you're going to be sweating profusely, your heart rate is going to increase, you're going to be quite panicked in fact or at least anxious.

There's a clear ceiling to caffeine's benefits. Going beyond 400 milligrams rarely provides additional performance gains and frequently increases negative effects like anxiety, jitters, increased heart rate, digestive issues, and crucially sleep disruption.
