Since the human body has been dependent on tobacco, once you quit smoking, there will be a period of withdrawal symptoms, such as panic, do not want to eat, nausea, vomiting, constipation, insomnia, etc., are due to the role of nicotine in the central nervous system. Generally, after a month of quitting smoking, the above symptoms will slowly ease, the body needs to buffer or adapt to the withdrawal of nicotine, so there is no need to worry, it is not particularly serious. If some withdrawal symptoms are more obvious, such as emotional irritability and nausea, you can choose to do something to make yourself feel happy, and at the same time try to keep your diet light. If constipation is severe, you can eat fresh vegetables and fruits rich in dietary fiber and drink more water. When the smoking addiction flares up again, you can eat some fruits to divert your attention.
