Have you tried Cepacol or gargling with salt water to help fight the infection?
I didn’t know Cepacol did anything but make your throat go numb, to be honest. And the salt…even if I weren’t afraid of the pain, that reminds me to pick some up the next time I’m at the store. I ran out yesterday, if you’d believe it!
I’m currently taking Mucinex D, Day/Nyquil Sinusex, and Zinc Tablets. My mom swears by the Zinc tablets for any kind of cold-like stuff and she threatened me from a couple of states away to get them. I found mine at GNC - you can get a big pack of them there for about twelve bucks.
Oh, and thank you for recommending vapor therapy earlier! I didn’t use vinegar, but I did make a pot of hot tea. It helped.
