It's starting to subside (knock on wood) without me visiting the doctor. I picked up some clotrimazole over the weekend and starting using that in addition to taking acidophilus. The combination must've done the trick because the little-yeasties-that-could are going away.
One interesting fact I found out this last week: BV can also be treated by acidophilus. So get some capsules, yogurt or whatever and take those if you've got the itchies. It will help regardless of what you have.
