You got through detox — so why do you still feel foggy, moody, or exhausted weeks later? It's likely post-acute withdrawal syndrome (PAWS), and understanding it makes it far easier to weather.

What PAWS is

After the acute physical withdrawal ends, the brain keeps rebalancing its chemistry for weeks or months. PAWS is the set of lingering symptoms during that process — it's a sign of healing, not of something going wrong.

Common symptoms

• Mood swings, irritability, or anxiety
• Low energy and trouble concentrating ("brain fog")
• Disrupted sleep and vivid dreams
• Waves of cravings that come and go

Why it matters

PAWS catches people off guard and can trigger relapse if they think "recovery isn't working." Knowing it's normal and temporary takes away its power.
