Hi J.
I do agree with the posts about changing your diet, however, while or if you decide to do that, for quick relief... try Capryl acid supplements.. I have changed up my diet, but prior to that, I suffered from constant yeast infections, I would take one capsule of those and then drink LOTS of water and bam... the infection would be gone within a day. however, you must drink lots of water.. the capryl kills the yeast and you need to flush it out of your system.. it's worth a try.. but also, getting your system to be more alkalin as oppose to acidic is also key.. you can do this by eating more raw foods and a plant based diet.. try and limit dairy and cooked foods, esp cooked meat.. the more alkaline you can get the body, the less problems you will have of yeast and other dilema such as fatigue, which can stem from yeast and other problems..
good luck
p.s. you can get the capryl acid at most healthfood stores in the vitamin section..
