Yeast infection

I went to the doctor a few weeks ago and I had a yeast infection. I was given the one time tablet difilicun or whatever it's called or spelled lol and I've taken it twice now and my yeast infection is going away!!! Im so frustrated. I don't wanna keep going back to the doctor because my copay is freaking expensive. Any suggestions?! I'm going crazy. It's not an overwhelming terrible yeast infection, it just isn't going away.
