It's been the third day I caught a cold. It started with a sore throat, probably because of the pack of potato crisps I ate while I did my essay.
The pain woke me up at 4am on Monday. So I decided to gargle with diluted apple cider vinegar. It worked! At least it wasn't as painful and I could speak. I tried this twice a day, for two days. And this morning when I woke up, the sore throat has gone 80%! I'll keep it up and see how it goes.
