How much do you question/challenge your FS?

Do most people just trust that their FS is doing absolutely everything they can?

I'm thinking of asking my FS what she would recommend if she wasn't constrained by law or or clinic rules - meaning are there things I'm missing out on trying because they are not yet approved here in Aus although they have been shown to have a positive impact on outcome elsewhere and/or the particular clinic doesn't believe in them (such as a particular drug or going to 3 day or blast transfers). I really want to know whether we are doing everything we can - or whether there are other options out there in this world that we should be considering.
