Quick answer

Nicotine withdrawal usually starts within 1 to 2 days of your last cigarette, is strongest in the first week, and most symptoms fade within 2 to 4 weeks. Cravings and increased appetite can last longer, and cravings can pop up months later. Withdrawal is uncomfortable but not harmful, and it doesn’t last forever.

Symptoms, phase by phase

A major review of tobacco abstinence (Hughes, 2007) found these are valid nicotine withdrawal symptoms: anger, anxiety, depression, difficulty concentrating, impatience, insomnia and restlessness, and that they peak within the first week and last 2 to 4 weeks. It lists constipation, cough, dizziness, more dreaming and mouth ulcers as possible effects. The review did not assess cravings or hunger, but Smokefree.gov lists cravings and feeling hungrier as common after quitting.

What makes withdrawal longer or shorter

How much and how long you smoked. Heavier, longer-term smokers often have stronger cravings.
Using quit medicines. Nicotine patches, gum and lozenges and other quit medicines can make withdrawal milder.
Triggers. Alcohol, stress and being around other smokers make cravings stronger.

When to see a doctor or get help now

You’re feeling very depressed, or having thoughts of harming yourself (call or text 988).
You have a mental health condition, are pregnant, or take regular medicines. Tell your doctor you’re quitting.
You’d like help choosing quit medicines. A doctor or pharmacist can advise.

Tapering

You can quit all at once or cut down first. Nicotine replacement (patches, gum, lozenges) lets you step the nicotine down gradually while you break the smoking habit. Free coaching is available at 1-800-QUIT-NOW (1-800-784-8669) and smokefree.gov.

Ride out cravings: distract yourself and avoid triggers for a while, as Smokefree.gov suggests
Keep healthy snacks around for the hunger
Cut back on coffee, tea and other caffeinated drinks for a while if you feel restless or jumpy, as Smokefree.gov suggests
