Cravings and withdrawal when you stop smoking

Most people have some nicotine cravings and withdrawal symptoms when they give up smoking.

These can be uncomfortable. But they are temporary - most symptoms stop after a month.

If symptoms do not improve or you’re worried, talk to:

  • your GP
  • a stop smoking advisor - they can give you information and advice on managing withdrawal

Cravings

The cravings you have depend on how often and how long you smoked.

Cravings for nicotine can start 30 minutes after your last cigarette. Individual cravings usually pass in 3 to 5 minutes.

You may get the most cravings 2 to 3 days after you stop smoking. Nicotine cravings gradually reduce the longer you stay quit. They usually improve 4 to 6 weeks after you stop smoking.

You may get unexpected cravings long after you quit smoking. These are usually related to things you associated with smoking. For example, seeing someone else smoke.

Deal with cravings by using the 4 Ds.

Distract

Distract yourself by focusing on something else.

Sleep problems - tips and self-help

Change in energy levels

Your energy might increase after you stop smoking. This is because more oxygen gets into your bloodstream as the carbon monoxide leaves your body.

But some people find they have less energy for a while. This is because the body stops producing adrenaline in response to nicotine. Low energy is temporary and improves after 2 to 3 weeks.

Constipation and nausea

About 1 in 10 people get constipation when they give up smoking. It can take 2 to 3 weeks to get better. Constipation can happen with nausea. Some people can have nausea without constipation.

Changes to your diet and lifestyle can help, such as:

  • eating lots of fruit, fibre and vegetables
  • drinking lots of water
  • doing physical activity every day

Ask a pharmacist about treatments to ease constipation.

Weight gain

Many people who smoke worry that quitting smoking will make them gain weight.

It can happen if you:

  • confuse cravings for nicotine with cravings for food
  • replace smoking with snacking

But you can avoid gaining any weight if you eat well and stay active.

If you’re worried about weight gain:

  • eat 3 balanced meals a day, with plenty of vegetables and fruit
  • prepare healthy snacks - such as celery, carrot sticks or fruit
  • drink water or low-calorie drinks and avoid sugary soft drinks
  • remind yourself that stopping smoking is the most important thing you can do for your health
