7 Common Smoking Withdrawal Symptoms And What You Can Do About Them

Everyone’s experience of trying to quit smoking is different, however, almost everyone will experience some nicotine withdrawal symptoms. When you stop smoking, your body and brain must adjust to life without nicotine.

Nicotine abstinence can be uncomfortable, but it will not hurt you unless you succumb and smoke a cigarette. The withdrawal symptoms will reduce over time as long as you don’t smoke.

1. Having Urges or Cravings to Smoke

When people stop smoking, almost everyone suffers cravings or wants to smoke. They can be moderate or can be overwhelming at times. One of the most crucial things you could do to stay successful is to figure out how to deal with cravings.

Ways to manage: There are a lot of things you may do to make them less of an issue. Quit-smoking medications, as well as other quitting methods, can be quite beneficial.

Cravings can be triggered by items that remind you of smoking, such as individuals you used to smoke with, a place you used to smoke frequently, or activities you used to do while smoking, such as drinking a cup of coffee.

A need might be triggered by a single thought or emotion. Other thoughts, such as remembering why you’re quitting, can help you get through a craving. Always keep in mind that you don’t have to yield to craving and that it will pass.

2. Feeling Irritated or Unnecessarily Angry

When you quit smoking, it’s fairly usual to feel irritated or grumpy. Many people who have never smoked are aware that this is a necessary element of stopping. It can be helpful to know that this is usual.

Ways to manage: Remind yourself that you’re probably feeling this way because your body is adjusting to being nicotine-free. Remind yourself why you’re quitting by taking a few deep breaths.

3. Feeling Jumpy and Restless

It’s okay to feel nervous or restless in the days or weeks following quitting. The rest of your body, like your mind, can get agitated without nicotine at first.

Ways to manage: Physical activity might help you shake off your nervousness. If you are feeling restless, you can take a walk around for a while. Reduce your consumption of tea, coffee, and some other caffeinated beverages. When you smoke, caffeine remains in your body for an extended time.

4. Having a hard time concentrating

It’s typical to realize that it’s tougher to concentrate in the first few days after quitting.

Ways to manage: Try to be patient with yourself, especially in the first few days after quitting. If at all possible, limit activities that need intense concentration.

5. Feeling Anxious or Depressed

Smokers are more prone than non-smokers to suffer from anxiety or sadness. After quitting smoking, some people experience mood swings for a brief period of time. This is something to be aware of, especially if you’ve ever suffered from anxiety or despair.

Smoking may appear to help with anxiety or sadness in some people, but don’t be fooled. Smoking may make you feel better in the short term, but this is because the nicotine in cigarettes relieves withdrawal symptoms, not because it helps with anxiety or depression.

Returning to smoking is a terrible method to deal with withdrawal symptoms and mood swings. The good news is that after a few months of not smoking, people’s anxiety and sadness levels are often lower than before they smoked.

Ways to manage:

– Be involved. Physical activity can help you feel better. Begin small and work your way up. When you’re down, this can be difficult. However, your efforts will be rewarded.

– Make a schedule for your day. Keep yourself occupied. Get out of the home if you can.

– Make friends with others. Keeping in touch or conversing with individuals on a daily basis might improve your attitude. Make an attempt to make friends with people who will support your efforts to quit smoking.

– Give yourself a reward. Engage in activities that you enjoy. Even the tiniest things add up to make you feel better.

– Speak with a medical professional. It’s essential to see a doctor if you don’t feel better in a few weeks or if your symptoms become intolerable.

If You Start Smoking Again, What Can You Do?

If you have a cigarette in your hand, don’t use it as an excuse to start smoking again. Removing yourself from the situation is the best thing you can do. Take a walk, take a deep breath, or sip some water, and consider whether you really want to start smoking again.

Don’t waste your time blaming yourself. Instead, see the cigarette as a hint that you need to rethink your quit plan.

Don’t give up if you’ve tried to quit smoking multiple times but have yet to succeed. It’s usual for people to try to quit smoking several times before finally succeeding.

Take a moment to think about what has worked for you in the past and what problems have prompted you to revert to smoking the next time you try to quit. Then develop preparations for what you’ll do if and when those urges resurface.


Smoking is a dangerous habit that can result in serious health issues and even death. When someone stops smoking, their body begins to repair and regain the vibrancy of a non-smoker over time.

Some effects, such as reduced blood pressure, are quickly noticeable. Other effects, such as the risk of heart disease, lung cancer, and lung illness, take years to return to non-smoker levels.

Each year of not smoking, on the other hand, reduces risks and improves wellbeing, rendering quitting an excellent choice for everyone who has started smoking.

Remember that doing something rather than doing nothing is always better than doing nothing to resist an urge. You are much closer to quitting smoking each time you resist an urge for cigarette use.
