What PAWS is

After acute withdrawal resolves, a second phase of symptoms can emerge weeks to months later. PAWS is caused by the brain slowly recalibrating neurotransmitter systems disrupted by chronic substance use.

Symptoms

Mood swings, anxiety, irritability, fatigue, insomnia, difficulty concentrating, reduced stress tolerance, and anhedonia. Symptoms come in waves, lasting days to weeks, with periods of feeling normal between them.

Duration

PAWS can persist for 6-24 months depending on the substance, duration of use, and individual factors. The waves become shorter and less intense over time.

Management

Understanding that PAWS is neurological, not psychological weakness. Exercise, proper nutrition, sleep hygiene, stress management, and ongoing therapy. Knowing that each wave passes and the overall trajectory is improvement.
