Recommended use: Drink black coffee and tea without sugar or sweeteners. Mind your caffeine intake.
If you have earned it, you can use cream in your coffee or tea (if you drink a lot of coffee, make at least some of it black).
Coffee contains caffeine, a powerful stimulant which can interfere with your sleep patterns. We recommend you don’t drink coffee after noon. If you can do without it, it would be best to avoid caffeine altogether, but for most people this is a good start.
