Tobacco deprivation has been found to produce many symptoms in chronic smokers. While increased craving for tobacco is most common, a variety of other symptoms have also been reported.
You may experience the following:
- Craving for tobacco
- Increased irritability
- Difficulty concentrating
- Increased hunger and eating
- Increased somatic complaints
- Increased episodes of coming awake during sleep.
Most of these withdrawal symptoms begin shortly after the onset of tobacco deprivation and peak 24–48 hours later.
