I put that it makes no difference, but that isn't quite true. Most often I would never schedule a social thing (actually I very rarely do anything social anyway, so yeah) but every month or so I need to give a professional presentation 1.5 hours after my therapy session. I have DID so it doesn't actually matter much... as soon as I am in that professional situation professional me does her stuff, and usually pretty well even if we have had a really traumatic session. It doesn't really work for social things, but if the need for performance is there I can usually rely on the me that needs to be there being there.
DID is just handy like that.
