To keep a steady energy level throughout the day, try replacing high doses of caffeine (such as a giant cup of brewed coffee) with more frequent low doses. Green tea is a great option. The easiest and cheapest way to run this experiment is to buy a box of green tea bags and try substituting two or three cups of tea for every cup of coffee you’d normally have. This keeps your energy level more consistent and steady throughout the day, avoiding the energy peaks and valleys you get from something super caffeinated like coffee.
