Dealing with nicotine withdrawal symptoms

All the symptoms you reported are withdrawal smoking symptoms. As the body eliminates the nicotine, the receptors that need it would reduce themselves slowly decreasing the withdrawal symptoms, too. The withdrawal symptoms, as in many other forms of chemical addiction, are strongest in the first five days of the quitting. Whatever you do, do not take a cigarette. That way you do not allow the nicotine receptors to reduce and you only prolong the quitting process and torture yourself more than is needed. You might ask your doctor for useful tips about what to do when you have the symptoms appear, or you can research them on the net.
