when I first started seeing the therapist I have right now she told me right off the bat that its pretty standard for people with dissociation problems not remembering things all the time and she would like to video tape me so that we have a record of my sessions, and any time I was having problems remembering what goes on during our sessions just give her a call and she would schedule a "viewing session" do that she and I could spend a session watching the tape and then talking about it. there have been many sessions I didn't remember and I called and we watched the tapes.

my opinion call your T and explain you lost some time and would like to schedule a time for you to come in and find out what happened and then talk about how you can fix it so that if you lose time again you have a plan and a way to know what happened.

the therapists around here are very happy to video and audio record sessions when the clients ask. a lot of places around here have permanent cameras installed in their therapy rooms in case any of their clients want to record their sessions.
