who has an essential oils downline.

I've had a cold for the past two weeks. I don't have time to go to the doctor, so I've been treating myself with nyquil and dayquil and over the counter stuff. It just keeps hanging on though. This morning when I was rummaging through the medicine cabinet I found some antibiotics that our vet gave us when we had our dog neutered. Those are safe for me to take for my cold, aren't they?
