- Relief from headaches may be a surprising perk for a smoker who quits smoking. Those exposed to secondhand smoke as well as regular smokers tend to have headaches; with the absence of cigarettes, those headaches can phase out.
- Smokers who quit smoking tend to become more sensitive to caffeine like canned soda or orange juice. This can cause new nonsmokers to become jittery and not be able to sleep well because they're not used to the new energy in certain drinks or fruits.
- Bad breath can ease from quitting smoking. Because of inhaling and exhaling cigarettes constantly, the mouth can become dry. Without cigarettes, the tissue in the mouth accepts mouthwash and toothpaste much easier and the breath tends to get better.
- Cigarette smoking tends to calm a person's nerves and makes them be still. Without cigarettes, a smoker who quits may seem overly hyperactive because he has been depending on cigarettes to make him be still.
