How fast after I quit smoking will my body start to change?

ANSWER

Here’s what you can expect after you finish your last cigarette:

  • 30 minutes to 4 hours: Nicotine's effects will wear off. You’ll start to crave another cigarette.
  • 10 hours: You’ll be restless, physically craving a cigarette, and wondering how to fill the time.
  • 24 hours: Irritability kicks in and your appetite goes up.
  • 2 days: You’ll have headaches as the nicotine leaves your system.
  • 3 days: The nicotine should be gone now. Your cravings taper off but anxiety rises.
  • 2 to 4 weeks: You still won’t have much energy, but the brain fog will clear and your appetite will settle down. Your cough, depression, and anxiety will also improve.
