Looks like you have gotten a LOT of good advice!
My youngest and I had an ongoing battle with thrush, and what finally worked for us was Gentian Violet, Grapefruit Seed Extract, Acidophilus, and All purpose nipple ointment.
We did the Gentian violet on both of us every night for about a week. I would sleep topless, and the baby in just a diaper, then we would place an old towel under us since it is messy stuff! I took Grapefruit seed extract and acidophilus orally, and after every nursing session I would spray some liquid grapefruit seed extract on my nipples, allow to air dry, then put on the all purpose nipple ointment. You can fine more information, and a
"recipe" for the ointment here:

Good Luck!
