The First Week After Quitting Smoking
A clear UK guide to the first week after quitting smoking, what to expect day by day and how to get through it.
The short answer
The peak. The first week is the hardest, though it is also where the worst passes.
The peak
Cravings and mood dips peak around days two to three.
The reward
By the end of the week you start feeling better.
The first week after quitting smoking
The first week is the toughest stretch, with getting through it a real milestone. Withdrawal usually peaks around days two and three with cravings, irritability and headaches, then eases over the rest of the week as your body adjusts and your breathing starts to feel easier. The hardest part passes quickly.
It helps to know the rough shape of the week so the tough days do not catch you out. The symptoms are your body adjusting and healing, not a sign anything is wrong, plus they fade as the days pass. This page walks through what to expect across the week, what is happening in your body and how to get through it.
Let us look at the week day by day, the changes and how to cope.
Having a realistic picture of the week ahead is one of the most useful things you can do. When you know the peak is coming and that it passes, the hard days feel less alarming and more like a stage you are moving through.
What to expect across the week
The week has a clear arc. The first day or two brings the first strong cravings, withdrawal peaks around days two and three with the most irritability and restlessness, then from day four the worst starts to ease and by the end of the week you tend to feel steadier.
- Days 1 to 2: first strong cravings, restlessness and a little edginess.
- Days 2 to 3: withdrawal peaks, with cravings and mood at their strongest.
- Days 3 to 4: nicotine has cleared and the worst begins to ease.
- Days 5 to 7: symptoms settle and breathing starts to feel easier.
Some changes are quietly encouraging. As the week goes on your sense of taste and smell start to return, your breathing eases as your airways relax, then you may notice a temporary cough as your lungs begin to clear, which is a sign of recovery rather than a setback.
These small wins are worth noticing while you push through the harder moments. Food tasting better or catching a scent you had not noticed in years is a reminder that your body is already rewarding you for the effort you are putting in.
How the first week tends to feel
Illustrative pattern, varies by person.
What is happening in your body
The discomfort comes with real repair underneath. Your body is clearing the last of the nicotine, your airways are relaxing so breathing feels easier, plus the tiny hairs that keep your lungs clear are starting to recover, which is why a short-lived cough is common.
The cravings and mood dips happen because your brain is adjusting to working without nicotine. This is uncomfortable but not dangerous, since it is the physical addiction beginning to loosen its hold. The temporary cough, the sharper taste and smell and the easier breathing are all signs that your lungs and senses are repairing. Knowing that the rough feelings sit alongside genuine healing makes the week easier to ride out.
If you have tried before and found the first week hard, it is worth remembering that each attempt teaches you something. Knowing your own pattern, then having a plan ready for the peak days, stacks the odds in your favour this time around.

How to get through the week
A few habits make the toughest week far easier. Plan for the days two and three peak, ride out cravings since each passes in minutes, keep busy, stay active, drink water and use nicotine replacement or vaping to take the edge off.
Be kind to yourself, since the early days ask a lot and a slower week with fewer demands helps. Keep away from your usual triggers where you can, fill the moments you would normally smoke with something else and lean on friends, family or a stop smoking service for encouragement. Remind yourself that reaching one week smoke-free means the hardest part is behind you. If low mood or anxiety feels severe or does not lift as the week goes on, it is worth speaking to your GP.
- Plan for the peak: expect days two and three to be the hardest.
- Ride out cravings: each one passes in a few minutes.
- Be kind to yourself: a slower week with fewer demands helps.
- Use support: nicotine replacement, vaping or a stop smoking service.

Why am I coughing more in the first week after quitting?
A short-lived cough in the first week is common and is a sign of recovery rather than a setback. The tiny hairs that keep your lungs clear are starting to work again, so your lungs begin clearing out mucus and debris from smoking. This usually settles over the following weeks. If a cough is severe or persistent, it is worth speaking to your GP.
How do I get through the first week without smoking?

Does the first week feeling rough mean something is wrong?
No. Feeling rough in the first week is your body adjusting to life without nicotine, not a sign anything is wrong. It is uncomfortable but not dangerous, since the symptoms fade as the days pass. They sit alongside real healing in your lungs and senses. If low mood or anxiety feels severe or does not lift as the week goes on, speak to your GP.
