When a person discontinues the use of stimulants, decreased energy is a common withdrawal symptom. Stimulants such as amphetamines and cocaine increase levels of neurotransmitters like dopamine and norepinephrine, leading to heightened alertness, increased energy, and euphoria while the drug is active in the system. When these substances are stopped, the body may respond with fatigue and lethargy as it adjusts to the absence of the stimulating effects. This can manifest as a significant drop in motivation and energy levels, leading to feelings of overall tiredness and decreased drive.

In contrast, increased alertness and euphoria would typically be associated with the use of stimulants rather than their withdrawal. Anxiety can certainly be a symptom related to withdrawal from various substances, but it is not as directly tied to stimulant withdrawal as the profound energy decrease experienced by many individuals.
