I have to take antibiotics regularly and sometimes get yeast infections as a result. Its miserable. I take probiotics regularly, wear cotton panties, and work on keeping my immune system strong but sometimes I still develop a yeast infection. I've learned that the one day treatments do not work at all of me, also - the treatments in ovule form are too harsh and do not seem to work 100%. I prefer the messier but more effective cream with the 3 day treatment. The antifungal pill helps, but isn't always 100%.. you may wish to try that combined with the 3-day treatment. If it is chronic and doesn't seem to always clear up, this is what my doctor recommended a few years ago. Take the antifungal pill and start the 7-day cream treatment regiment. After you have finished the 7-day treatment, another antifungal pill. This should really "knock it out of your system." In the mean time, drink lots of fluid and get lots of rest - many say that the dying off yeast can be hard on your system. You might want to check out some of the books in the "Yeast Connection" series to see what they recommend if it continues to be chronic.
