Sutra 23 - Avoid Coffee after 4 PM

Coffee interferes with your sleep cycles and can leave you tired and with less focus, the next day. Avoiding coffee or sugars after 4 PM ensures that the body can prepare to wind down. If there is work pressure and you need to stay awake, make sure you drink warm water with some lemon instead of coffee.

Another simple trick to increase your alertness is to stretch your ears with your hands. This helps to increase circulation around your forehead and increases alertness.
