Can caffeine make you more tired?
Is it possible to develop a tolerance to caffeine?
Yes, it is possible to develop a tolerance to caffeine over time. This means that you may need to consume more caffeine in order to achieve the same effects that you used to feel with a lower amount. Tolerance to caffeine can also lead to withdrawal symptoms if you suddenly stop consuming it, such as headaches, irritability, and fatigue.
