Nicotine withdrawal symptoms
Physical withdrawal from nicotine is temporary, but it can be uncomfortable while it lasts. Quitter’s flu is a term used to describe this phase of smoking cessation because nicotine withdrawal symptoms often mimic a cold or a mild case of the flu. Understanding what to expect when you quit smoking will help you move through this stage more easily.
The following list contains commonly reported symptoms of nicotine withdrawal. Most people experience some of these, but rarely all of them. Each person goes through this phase of recovery from nicotine addiction a little differently. But for most people, these discomforts are short-lived.
- Cravings to smoke
- Irritable, cranky
- Inability to concentrate
- Sore throat
- Constipation, gas, stomach pain
- Dry mouth
- Sore tongue and/or gums
Check with your doctor if you’re concerned about a physical reaction you’re having to smoke cessation, or if nicotine withdrawal symptoms persist.
