Be advised that we all may suffer different symptoms when we quit. Everyone's body will be different and so will the symptoms.
Your hands and fingers may tremble slightly and you may experience increased perspiration. However, the tremor is usually minor, and will subside as your body gets used to not smoking.
How long will this last? The first few weeks after quitting.
Tips to help: Frequent warm baths or showers can help dispel both the perspiration and the tremor. If you are concerned, consult your doctor to determine whether it is severe enough to warrant medication.
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.
