An uncomfortable sensation of queasiness and stomach discomfort that may or may not lead to vomiting, often occurring during the onset phase of many substances.

Restless legs is an uncomfortable neurological effect characterized by an irresistible compulsion to move the legs (and sometimes other limbs) to relieve unpleasant crawling, aching, or tingling sensations, particularly during periods of rest or inactivity.

A state of heightened physical and mental energy characterized by increased wakefulness, elevated motivation, and a subjective sense of vigor that pervades both body and mind. Users often report feeling electrically alive, with a buzzing readiness to move, talk, and engage that can range from a pleasant caffeine-like lift to an overwhelming, jittery compulsion to act.

Intense feelings of apprehension, worry, and dread that can range from a subtle background unease to overwhelming panic attacks with a sense of impending doom, often amplified by the substance's intensification of one's existing mental state.

A persistent state of low mood, emotional numbness, hopelessness, and diminished interest or pleasure in activities, often occurring during comedowns, withdrawal, or as a prolonged after-effect of substance use.

A heightened sense of drive, ambition, and willingness to accomplish tasks, making productive effort feel rewarding and almost effortless.

A renewed sense of physical vitality, mental freshness, and emotional restoration that can emerge during or after a substance experience. The individual feels as though accumulated fatigue, stress, and mental fog have been cleared away, leaving behind a state of refreshment and renewed energy that is often compared to waking from deep, restorative sleep or returning from a revitalizing vacation.

An increased ability to stay awake and alert without the desire to sleep. Distinct from stimulation in that it does not elevate energy above a naturally rested baseline.
