Don't know if you ran across it yet, but Mattk3's Ascaris123 protocol is worth a read. He talks a lot about many different supplements/meds and the effects he felt... and about interactions and ramping dosages up and down. I don't believe he mentions fluconazole, but it might be in there. Might be worth a search in the forums or online too. I don't remember where or how I learned that fluconazole was synergistic with albendazole.
The other thing that comes to mind is checking in with Dr. Yu about the ear ringing.
Just re-read your post... didn't realize you were taking fluconazole plus itraconazole... that sounds weird because I thought they did the same thing. Seems like one or the other. Curious why he put you on both of them. Anyways, backing off seems reasonable. Ringing in the ears along with crazy lights doesn't sound fun.
