I always feel really nauseous if I’m having diarrhea and eating coconut oil. What I when this happens is just stop using coconut oil. Fatty things are usually hard to process for your liver. I think it is normal that you have stomach issues if you’re having diarrhea. This is a natural defence mechanism from your body.
Your symptoms seem much worse than mine. You don’t need to rush into the diet. I’d lower the amount of antifungals for now. It’s all about how good you feel with using it.
Wait for an answer from Able. He will know it better.
