You may feel edgy and irritable. You also may get angry or upset faster, have trouble concentrating and feel hungrier than usual. Keep in mind the worst symptoms will be over in a few days. However, you may still have cravings for tobacco. Those cravings will have less to do with nicotine addiction and more to do with the habit of tobacco use.
Some people gain a few pounds.
Other people lose weight. The main reason some people gain weight is because they eat more food as a substitute for smoking. You can avoid gaining weight by watching how much you eat, staying busy and working out. Pick a stop date. Choose a date 2 to 4 weeks away so you can get ready to quit.
