candybear, try the over the counter stuff first. It gets rid of 90% of my yeast infections. I use the creams you insert with an applicator or the suppositories. Use them for the recommended number of days, not just until you feel better. If those don't completely cure it for me, I do a second course. If it's still not gone, I call the doctor and get an oral prescription, usually just a pill for 1-3 days. Works really well, but they are really strong, so I like to try the OTC stuff first.

Good luck.
