You may experience some occasional dizziness during your quit. You are now absorbing more oxygen through your lungs than your body has been accustomed to. This dizziness may come once or twice a day for a few days. It usually lasts only one or two seconds, and is gone before you have time to do anything about it.
How long will this last? The first few days after quitting.
Tips to help: Take extra caution in the common physical things you do. Practice standing up or moving at a slower pace.
Racing heart could be due to anxiety. Chemicals in tobacco smoke affect your entire central nervous system. Because these chemicals have been messing with your nervous system, quitting can cause a feeling of nervousness, which sometimes lasts for a few days. And, when your central nervous system gets back in line, you may find that you have a keener sense of smell, taste, hearing, colour and depth perception.
Tips to help:
Try relaxation techniques, such as deep breathing and exercise. Physical activity can also be helpful in expending that extra anxious energy.
If you have a symptom that persists or seems worse than you expected, you should immediately consult a doctor. Its possible that your smoking has been masking symptoms of some illness, and when you stop smoking the symptoms abruptly become noticeable.
How are you feeling today?
