Thanks for the responses, folks
Well, a quick update:
I lasted three days on the super-duper oregano oil. Once I tried it with juice (blech), and the other dosages I just put in a giant glass of water, held my nose and drank it. By the sixth glass, I couldn't take it anymore. I've even had to move the tiny jar of the stuff to the back of my house, because I could smell it all the time in my kitchen. It's going to be a LONG time before I ever care to eat anything with oregano in it again, lol.
Aside from the really bad taste, I just felt rotten drinking it. My stomach hurt, loose stools, heartburn, headaches. I kept waiting for it to get better, but it didn't.
They guy at the health food store thought three days would be enough to clear up a normal, antibiotic-induced yeast infection, but it didn't help it at all. My doc phoned me in a prescription for Diflucan which cleared it up in about 48 hours.
Sooo, anywhoo, I tried, but I ended up back with Diflucan.
