Depends: what would be SAFEST is to limit your caffeine to 1-2 servings per day (about 100 mg of caffeine). Above that, whether from coffee, colas/sodas or energy drinks, caffeine can increase anxiety, insomnia, elevate pulse and blood pressure and complicate high blood pressure etc. If you don't guess right on the equivalency, you may get headaches with the switch.
