Understanding Substance Withdrawal

What to expect when stopping substances — and how to stay safe.

What Is Withdrawal?

Withdrawal occurs when your body has become dependent on a substance and you reduce or stop using it. Symptoms can range from mild discomfort to medically dangerous.

Never try to withdraw from alcohol, benzodiazepines, or opioids without medical supervision — these can be life-threatening.

Common Withdrawal Experiences

Anxiety, irritability, and restlessness.

Difficulty sleeping.

Physical symptoms: sweating, shaking, nausea.

Intense cravings.

Mood swings and depression.

Difficulty concentrating.

Flu-like symptoms.

Staying Safe

Always seek medical advice before stopping substances you've been using regularly.

Gradual reduction is usually safer than stopping suddenly.

Your GP can refer you to specialist addiction services.

Stay hydrated and try to eat regular meals.

Support groups like AA, NA, or SMART Recovery provide ongoing help.

Withdrawal is temporary — it does get better.

Having someone with you during the worst days is important.
