Symptoms, phase by phase

SAMHSA’s 2010 advisory on protracted withdrawal says most people in treatment don’t immediately feel better after stopping, and that symptoms may be felt for weeks, months and sometimes years. Its list of possible symptoms includes anxiety, sleep difficulties, short-term memory problems, persistent fatigue, difficulty concentrating, cravings, impaired self-control, anhedonia (reduced ability to feel pleasure), dysphoria or depression, irritability, unexplained physical complaints and reduced interest in sex. For alcohol, it says sleep abnormalities can persist for 1 to 3 years. For opioids, anxiety, depression and sleep problems can last weeks or months. For benzos, fluctuating symptoms may last months but gradually subside. For marijuana, sleep problems and strange dreams persisted at least 45 days in studies. SAMHSA stresses that research is limited and no consensus definition exists, which is why it gives no timeframes for protracted withdrawal.

Acute withdrawal (for comparison): Alcohol 5 to 7 days; opioids 4 to 10 days; stimulants 1 to 2 weeks; nicotine 2 to 4 weeks; benzos 1 to 4 weeks (SAMHSA)

• Substance-specific withdrawal symptoms

Early post-acute: The first weeks to months after acute withdrawal

• Anxiety, irritability
• Sleep difficulties
• Persistent fatigue
• Trouble concentrating and making decisions
• Cravings

Lingering or returning symptoms: Months; SAMHSA notes some people feel clear for a month or two before symptoms return

• Low mood or flat feelings (anhedonia)
• Short-term memory problems
• Reduced interest in sex
• Unexplained physical complaints

Gradual recovery: With long-term abstinence, symptoms fade; alcohol-related sleep changes can last 1 to 3 years

• Symptoms wax and wane and become less frequent

What makes withdrawal longer or shorter

• The substance. Alcohol has the best-documented protracted symptoms; data for other drugs is scarcer.
• Co-occurring conditions. SAMHSA says it can be hard to tell PAWS from depression, anxiety or a brain injury, so get assessed.
• Sleep, stress and activity. SAMHSA recommends sleep habits, exercise and not overloading yourself.

When to see a doctor or get help now

• Symptoms are getting worse instead of slowly better, or you can’t function.
• You think it might be depression or anxiety rather than withdrawal; a mental health assessment helps.
• Call or text 988 for thoughts of suicide.
• You’re at risk of relapse; contact your treatment provider or SAMHSA at 1-800-662-4357.

Tapering

PAWS isn’t something you taper. It happens after the acute phase. If you’re still stopping a medicine such as a benzodiazepine or antidepressant, a slow, prescriber-led taper may reduce symptoms.

Tips for getting through it

• Expect ups and downs; SAMHSA says symptoms can be managed and won’t last forever
• Keep a regular sleep schedule, exercise early in the day and limit caffeine
• Use to-do lists and routines for memory and concentration problems
• Don’t overload yourself; recovery is enough work
• Join a mutual support group, and look for one that accepts prescribed medications if you take them
• Celebrate small wins

Frequently asked questions

How long does PAWS last?

SAMHSA doesn’t give a timeframe because research is limited. Symptoms can last weeks to months, and sometimes longer, gradually becoming less frequent.

Is PAWS a real diagnosis?

Not officially. SAMHSA notes it isn’t in the DSM because research is limited and there’s no agreed definition, although clinicians observe and patients report these symptoms after acute withdrawal.

Why do I feel worse a month after quitting?

SAMHSA says some people have a clear stretch for the first month or two and then develop symptoms again. That’s described in PAWS and doesn’t mean you’ve failed.
