I moved from 1 to 2 to 3 over a year as we both discovered it was more effective. I also moved from the chair to the sofa. I tried laying down once to try it as an analyst's couch but didn't like it.

However I did it again organically a few times when a certain part was to the fore and that's the position she likes. But I change the way I sit or lie at will.

I've no idea what my therapist prefers. Prob the chair as that is what we started with. But if I wanted to stand in my head I'm sure she wouldn't have an issue - we would talkkkkkkkkk about it though!
