I Can’t believe I picked up a summer cold
It's been 20+ years since I picked up a cold in the summer. Being susceptible to germs in a new environment is normal. New job, new city, new apartment, etc...
May I suggest a remedy?
I discovered Zicam years ago. Zinc in any form works well. The sooner you use, the better. A downside of Zinc, it can upset the stomach. In fact, I have an upset stomach right now.
