The old fashioned kinds?
Happenstance, I have not had a cold yet since March?
I have phlegm morning, and evening from blood pressure pills.
You folks?
Toxins in the lungs. The lungs are one of multiple pathways of how the body is designed to get rid of toxins. It picks up household pollutants through night too. Usually molds and dust.
Here's a idea that some of the atheists here will accuse me of practicing medicine. Write a note as a reminder and put it somewhere in the kitchen where you first go every morning, ie. coffee pot.
Have a glass jar of fresh water, a quart to start the day.
See if this works for you too.
Don't use it for coffee. Use before drinking it or breakfast. The body is dehydrated in the AM and blood thins with water. The phlegm thins and clears out easier too.
