I use to have the same problem, my doctors gave me all the same things to try, it would work for a while, then come back again,,, what I did is this,,, start watching what you eat that has yeast in it. especially bread products, pizza's all that good stuff, I had to limit myself in those things. once on got on a routine of checking that and limited myself I found the infections where less, then went to none. I have not had an infection in almost 1 1/2 years. good luck, it worked for me, and maybe you too!!!
