Many smokers feel that smoking helps to calm them down and reduce stress. This is because your body is used to nicotine and relies on it to feel normal. To find out more see stress and smoking.
Smoking and caffeine
When you stop smoking, you feel the effects of caffeine more because chemicals in cigarettes make your body get rid of caffeine faster. If you quit without reducing your caffeine intake, you will have higher levels of caffeine in your body which can make you feel restless, irritable and sleepless.
When you quit smoking, try to reduce your intake of caffeine, e.g. drinks like coffee, tea, cola, chocolate.
