Just found this on an American site. May be interesting to some of you. (warn you its a bit of a long blog)
Nicotine Withdrawal Symptoms & Recovery
The first few weeks after quitting smoking are usually the most difficult and it's safe to say that it normally takes at least 8-12 weeks before a person starts to feel comfortable with their new lifestyle change of being an ex-smoker. Withdrawal from nicotine, an addictive drug found in tobacco, is characterized by symptoms that include headache, anxiety, nausea and a craving for more tobacco. Nicotine creates a chemical dependency, so that the body develops a need for a certain level of nicotine at all times.
unless that level is maintained, the body will begin to go through withdrawal. For tobacco users trying to quit, symptoms of withdrawal from nicotine are unpleasant and stressful, but only temporary. Most withdrawal symptoms peak 48 hours after you quit and are completely gone in six months.
When you are experiencing symptoms of recovery (withdrawal), remind yourself of why you are quitting; write your reasons on a card and keep it with you. Remind yourself that whatever discomfort you are experiencing is only a tiny fraction of the probable discomfort associated with continued smoking (i.e. Painful diseases like cancer, surgery, chemotherapy, emphysema etc.).
Withdrawal in the First Two Weeks
Because the first two weeks are so critical in determining quitting failure rates, smokers should not be shy about seeking all the help they can during this period.
Withdrawal symptoms begin as soon as four hours after the last cigarette, generally peak in intensity at three to five days, and disappear after two weeks. They include both physical and mental symptoms.
Physical Symptoms.
During the quitting process people should consider the following physical symptoms of withdrawal as they were recuperating from a disease and treat them accordingly as they would any physical symptoms:
Tingling in the hands and feet
Sweating
Intestinal disorders (cramps, nausea)
Headache
Cold symptoms as the lungs begin to clear (sore throats, coughing, and other signs of colds and respiratory problem)

Nicotine creates a chemical dependency, so that the body develops a need for a certain level of nicotine at all times. Unless that level is maintained, the body will begin to go through withdrawal similar to alcohol addiction withdrawal. For tobacco users trying to quit, symptoms of withdrawal from nicotine are unpleasant and stressful, but only temporary. Most withdrawal symptoms peak 48 hours after you quit and are completely gone in six months.
Mental and Emotional Symptoms.
Tension and craving build up during periods of withdrawal, sometimes to a nearly intolerable point. One European study found that the incidence of workplace accidents increases on No Smoking Day, a day in which up to 2 million smokers either reduce the amount they smoke or abstain altogether.
Nearly every moderate to heavy smoker experiences more than one of the following strong emotional and mental responses to withdrawal.
Feelings of being an infant: temper tantrums, intense needs, feelings of dependency, a state of near paralysis.
Insomnia
Mental confusion
Vagueness
Irritability
Anxiety
Depression is common in the short and long term. In the short term it may mimic the feelings of grief felt when a loved one is lost. As foolish as it sounds, a smoker should plan on a period of actual mourning in order to get through the early withdrawal depression.
Causes, Incidence and Risk Factors...
Almost all people who try to quit have some form of nicotine withdrawal. Generally, the longer one has been a smoker and the more nicotine and higher number of cigarettes consumed, the more likely it is that withdrawal symptoms will occur and the more severe they are likely to be. Furthermore, people who are regular smokers tend to have particularly strong cravings and worsening of withdrawal symptoms at certain times, places, or situations associated with smoking. Tobacco contains nicotine, an addictive drug, and smokers become addicted. If you quit abruptly, you will go through the physical and psychological effects of drug-withdrawal, These may include intense food cravings, jittery nerves, anxiety, short temper, depression, and sleeplessness. The addiction-withdrawal symptoms will be worst the first week and less severe during the second. After a month, most of the withdrawal symptoms will be gone, If you quit gradually, the withdrawal may be less intense but more prolonged, This is why many experts recommend quitting abruptly!
Symptoms:
The common symptoms include an intense craving for nicotine, tension, irritability, headaches, difficulty in concentrating, drowsiness and trouble in sleeping, increased appetite and weight gain. A milder form of nicotine withdrawal involving some or all of these symptoms can occur when a smoker switches from regular to low-nicotine cigarettes or significantly cuts down.
Treatment:
There are several strategies for treating nicotine withdrawal. Nicotine supplementation in the form of gum or patch can be helpful. A variety of other agents have also been used with some success in maintaining abstinence and reducing withdrawal symptoms.
These agents include clonidine, antidepressants such as fluoxetine (Prozac), and buspirone (Buspar). Bupropion (Zyban) was approved in 1996 by the Food and Drug Administration as a treatment for nicotine dependence. Using buproprion or nicotine replacement therapies alone doubles the odds of successful quitting. Using a combination of these methods increases success rates even more. Buproprion and other antidepressants are not habit-forming, and may help reduce the possibility that nicotine withdrawal may lead to depression. Since nicotine itself has antidepressant effects - and many smokers unknowingly smoke to self-medicate depression - use of antidepressants to relieve withdrawal may be particularly helpful. A screening for depression may also be helpful to ensure proper treatment and increase the odds of maintaining abstinence. People trying to quit smoking often become discouraged when they don't succeed at first. Research shows that the more times you try, the more likely you are to succeed - so don't give up!
Expectations (prognosis):
Nicotine withdrawal is short-lived and should pass in time. While withdrawal is the most uncomfortable part of quitting, the real challenge is beating long-term cravings and staying abstinent.
Complications:
The most likely complication will be a return to smoking. Weight gain due to increased eating also may occur. This is much less unhealthy than continuing to smoke, and those with concerns about weight should address them while quitting so that they do not undermine their attempts to stay away from cigarettes.
Calling your health care provider:
See your health care provider if you wish to stop smoking, or have already done so and are experiencing withdrawal symptoms. Your provider can help provide treatments, some of which are only available by prescription.
Hopefully I think I'm starting to come out of that phase now, hope so anyway.
