Strategies for Effective Caffeine Use

Use Caffeine before a period of time that you are likely to experience fatigue.

For example, during the 3 am to 5 am period of the day or any other time when you might be prone to experiencing fatigue.

Remember that caffeine can take 15-30 minutes to take effect.

However, the effects of caffeine can last 3 to 4 hours.

Caution, do not take caffeine at least 3-4 hours before bedtime.
