IFS Beginner and Psychedelics

I'm a beginner with IFS. I'm doing it on my own for now, possibly switching to a therapist who is well versed soon if I can find one in my area that takes my insurance. I am also interested in psilocybin therapy. It's not an option for me to do with with a therapist, unfortunately so I am considering trying on my own. I was thinking of starting off low in terms of dose to ease into it and get a feel for it.

I wanted to ask - for those who have done it, what do you do to prepare if you want IFS to be a part of it? I've seen segments on podcasts and things of Richard Schwartz talking about making sure the parts are on board and basically asking permission from the protectors beforehand. How should I go about that? Do I just try to ask them and see what comes up and reassure them if they express any concern? Have you done exercises during the session or do you wait until afterwards?

I'm starting out with identifying parts and working with them. I've made a little bit of progress but still have a long way to go. I understand that doing this alone is not ideal, but I'm trying to work with what I have.
