What are the withdrawal symptoms when quitting smoking?

Here are some common withdrawal symptoms you can expect to experience when quitting smoking:
  • Irritability: Cause -- Your body craves nicotine. This can last 2 to 4 weeks. For relief, take walks and hot baths, use relaxation techniques and consider nicotine replacement.
  • Fatigue: Cause -- Nicotine is a stimulant. This can last 2 to 4 weeks. For relief, take naps, don't push yourself and use nicotine replacement.
  • Insomnia: Cause -- Nicotine affects brain-wave function and influences sleep patterns. Coughing and dreams about smoking are common. This can last up to 1 week. For relief, avoid caffeine after 6 p.m. and use relaxation techniques.
  • Cough, Dry Throat, Nasal Drip: Cause -- Your body is getting rid of mucous that has blocked airways and restricted breathing. This can last a few days. For relief, drink plenty of fluids and try cough drops.
  • Dizziness: Cause -- Your body is getting extra oxygen. This can last 1 or 2 days. Take extra caution when moving. Change positions slowly.
  • Lack of concentration:  Cause -- Your body needs time to adjust to not having constant stimulation from nicotine. This can last a few weeks. For relief, plan your workload accordingly. Try to avoid additional stress during your first few smoke-free weeks.
  • Tightness in chest: Cause -- Probably due to tension created by your body's need for nicotine. It may also be caused by muscles sore from coughing. This can last a few days. For relief, use relaxation techniques, especially deep breathing. Nicotine replacement may help.
  • Constipation, Gas, Stomach Pain: Cause -- Intestinal movement decreases for a brief period following quitting smoking. This can last 1 or 2 weeks. For relief, drink plenty of fluids. Add fruits, vegetables and whole grain-cereals to your diet.
  • Hunger: Cause -- Craving for cigarettes can be confused with hunger pangs or with desire for something in the mouth. This can last up to several weeks. For relief, drink water or low-calorie liquids. Be prepared with low-calorie snacks.
  • Craving for a cigarette: Cause -- Withdrawal from nicotine, a strongly addictive drug. This is most frequent during the first 2 to 3 days but can happen occasionally for months or years. Wait out the urge, which usually lasts only a few minutes. Distract yourself. Make a phone call. Walk around the block.
