Oh! I forgot to tell you how to avoid this sort of infection in the future!
When you're taking antibiotics, keep in mind that this type of medication kills back many, many of the tiny critters in your internal eco-system, not just the nasty ones that are making you sick. And that kind of general die-back leaves the door open for whatever survives to take advantage of the situation. So take steps to repopulate your insides with beneficial or at least benign flora, such as taking doses of acidolphilus between my doses of medication, eating lots of yogurt, etc.
Since I've started doing this, I have not had one single yeast infection. (Knock on wood.)
