Here’s an overview of why you’re feeling cold symptoms and what you can do to cope:
Withdrawal sign or symptom
Cough with phlegm
Post nasal drip
Mucus that drips from the back of your nose into your throat
Why you’re feeling it
When you first quit, you might notice a lot of coughing and phlegm. This is a good sign. Your lungs are trying to clear out the tar and other dirt trapped inside your airways. Help your lungs by allowing yourself to cough and spit this stuff out.
How long it lasts
A few days
What you can do
Drink lots of water to thin out the mucus and make it easier to bring up. Cough it up or swallow it.
