My T takes a few notes at the beginning of our sessions, general observations about mood, etc. He must do the rest between sessions. My T reads his notes to me from time to time far various reasons. They really aren't terribly exciting. They tend to be quick, rather general notes about my mood, topics we discussed, or insights that were made. Nothing I don't already know anyway. He usually writes I guess 5-10 lines about each session, much of it in phrases and all. It really isn't a big deal or mystery. They come in handy when we are trying to remember where we were on a certain topic because my memory of our sessions is horrible, he uses them to trace when a mood episode started, etc.
