Advice - what more should I be doing?

I joined the Facebook group since that is what keeps getting recommended to me but it is very hard to just ask a simple question there. They put me in a private group with someone and I have no idea if they are a vet or what but they need a thousand different things to even answer a question. That’s fine but I don’t have access to all of that information without getting it from my vet.

They did tell me that “I would be worried about supportive care or even whether or not the dosage is correct and accounts for all of her symptoms. FIP treatment is not as simple as just giving a pill and most vets are just starting to learn about the process.”

What are you all doing in addition to giving the pills? My vet seems very knowledgeable about the treatment and does not seem concerned, but this response is making me question what else I should be doing.
