The timeline at a glance
| When | What you might notice |
|---|---|
| First hours | First cravings, restlessness and irritability as nicotine levels fall. |
| Days 1 to 3 | Often the hardest stretch: strong cravings, irritability, anxiety, trouble concentrating, headaches and poor sleep. |
| Days 4 to 7 | Symptoms are still noticeable but start to ease. Appetite often increases. |
| Weeks 2 to 4 | Most physical symptoms fade. Mood, focus and sleep settle. People who smoked may cough more for a while as their lungs clear. |
| 1 to 3 months | Occasional cravings, mostly tied to old triggers like coffee, alcohol or stress. |
| After 3 months | Cravings become rare and much easier to ignore. |
Everyone is different. How much nicotine you used, and how constantly, affects how strong withdrawal feels.
Common symptoms and what helps
- Cravings: each one usually passes within a few minutes. Ride it out with urge surfing or a short distraction.
- Irritability and anxiety: slow breathing, exercise and telling people around you what you're going through.
- Trouble concentrating: break tasks into smaller pieces and plan lighter days for your first week.
- Poor sleep: cut back on caffeine, which can feel stronger after you quit, and keep a regular bedtime.
- Increased appetite: regular meals, filling snacks and plenty of water.
- Low mood: usually temporary. Keep in touch with people and stay active.
Nicotine replacement therapy eases most of these symptoms by giving you controlled, reducing doses of nicotine. Ask a pharmacist which product suits you.
Is it different for vapes, cigarettes and pouches?
The withdrawal itself is the same, because it comes from nicotine. What differs is the habit around it. Vapes and pouches are often used constantly through the day, so people may notice cravings in more situations at first.
How long nicotine stays in your body
Nicotine itself clears from the blood within a few days of stopping. Its by-product, cotinine, can be detected for longer. Physical withdrawal mostly follows the same pattern: worst early on, then fading as your brain adjusts.
When to talk to a doctor
Speak to a doctor if your mood becomes very low or you have thoughts of harming yourself, if you're pregnant, or if you have a heart condition. If you take regular medicine and you've stopped smoking, tell your doctor, because tobacco smoke changes how some medicines are processed.

Can nicotine withdrawal cause anxiety?
Yes. Anxiety, irritability and restlessness are common in the first weeks. They usually ease as withdrawal passes. Many people find their anxiety ends up lower than before they quit.
Why am I so hungry after quitting nicotine?
Nicotine suppresses appetite and changes how you taste food, so appetite often rises after quitting. Regular meals and filling snacks help.
