I was just recently diagnosed with DID. I too forget what goes on in sessions and I hope I'll be able to talk to my psych about it and see if he has suggestions. I am also interested in what ideas people here have.
Sorry I don't have any solutions for you but hopefully others will. I'm still getting use to the idea that I have MPD. I've always suspected but actually have two dr's diagnose me is scary. My alters are coming out more.
