I’m so sorry, I know how painful and annoying thrush is. I didn’t get it this time around, but did with my first. We tried a round of nystatin which didn’t do much, so went on to diflucan which helped for about a week and then it returned worse than ever. The only thing that worked for us is gentian violet, vinegar rinses, boiling the crap out of everything(paci,bottles,pump parts) and bleaching bras until they were basically see through. I also took acidophilus too. HTH!
