While caffeine can increase your alertness so that, for example, you can drive late at night, it has a variety of side effects. Some are short-term and come with the rush of energy you get during the first few hours afterwards, like nervousness or anxiety; however, many of these effects are also long term in effect, such as caffeine resistance or reduced fertility (for females). This is one of the few performance enhancing substances that is actually permitted (in competitions) most likely due to its lesser effects on performance and decreased severity of side effects.
