Don't mess with these drugs. I don't know of anyone who's overcome candida for good just with pharma antifungals, they tend to create more problems long term!
Try the Turpentine + Sugar protocol it is incredibly effective based on what I've read, I just ordered some myself.
Iodine + borax helps gradually and will keep candida away, very cheap.
Castor oil can be very helpful for cleaning out intestines as well, also very cheap.
These things work together, and of course stick to a good diet.
