oral thrush

we've been dealing with thrush for about 3 weeks now and I'm so done 😭 I don't wanna give up breastfeeding so I'm trying everything to not give up. I'm currently on diflucan and my son is taking Nystatin but this is already his second bottle. is there anything I can do to help get rid of the thrush? I hate that I have to keep giving him medicine😭😭 I just want it to be gone
