Nicotine withdrawal symptoms: what to expect
Nicotine withdrawal brings a mix of cravings, irritability, anxiety, trouble concentrating, restlessness, low mood, a bigger appetite, and disrupted sleep. It usually starts within hours of your last cigarette or vape, peaks around day 3, and eases over the next two to four weeks. None of it is dangerous, and all of it passes.
The full list, and when each one shows up
| Symptom | Usually starts | Eases by |
|---|---|---|
| Cravings | Within hours | Shorter and rarer after 2 to 4 weeks |
| Irritability, frustration | Day 1 | 2 to 4 weeks |
| Anxiety, restlessness | Day 1 to 2 | 2 to 4 weeks |
| Trouble concentrating | First few days | 2 to 4 weeks |
| Low mood | First week | Usually within 4 weeks |
| Increased appetite | First week | Can last longer |
| Trouble sleeping | First few days | 1 to 2 weeks |
Not everyone gets every symptom, and how strong they are depends on how much and how long you used nicotine. Most people find the mental symptoms, the irritability and the fog, harder than any physical feeling.
Why it happens
Nicotine has been doing a job in your brain, nudging dopamine and keeping you feeling level. Take it away and your brain has to relearn how to do that on its own. The symptoms are that adjustment happening. Because nicotine clears the body within a few days, the physical push is front-loaded, which is why day 3 tends to be the hardest.
What actually helps
Cravings pass in three to five minutes whether or not you smoke, so the goal is to get through the wave, not to fight it forever. Water, a short walk, and keeping your hands busy all buy time. Nicotine replacement (patches, gum, lozenges) can take the edge off the physical side. A GP or pharmacist can point you to what fits your situation.

What are the symptoms of nicotine withdrawal?
Common nicotine withdrawal symptoms are strong cravings, irritability or frustration, anxiety, trouble concentrating, restlessness, low mood, increased appetite, and difficulty sleeping. Most people also feel a general sense of being on edge. The symptoms are your brain adjusting to working without nicotine.
When do nicotine withdrawal symptoms start and peak?
Symptoms usually begin within 4 to 24 hours of your last cigarette or vape, peak at around 3 days (72 hours), and then ease over the following 2 to 4 weeks. Cravings can appear later as short, occasional urges triggered by habits or situations.
How long does nicotine withdrawal last?
The physical symptoms of nicotine withdrawal are usually strongest in the first week and mostly settle within 2 to 4 weeks. Occasional cravings can come and go for longer, but they get shorter and less frequent over time.
