Nipple Thrush :(

Jess • Married to the love of my life, totally smitten with our little girl and boy.
Good times...at least I know now what's been causing our pain despite a correct latch. 
My daughter is on Nystatin and I'm on Diflucan. 
But my nipples are so sore and I'm afraid of getting cracks again which we already worked through once. I read that I can't use Lanolin or expressed breastmilk. What can I use to keep them from drying out and cracking?
