I used to have the same experience (i.e. forgetting) when I first started my SRT although I generally don't forget anymore. I believe it's because as my activation has come down I'm more present and I can remember more.
One thing that really helped me with my current therapist (she doesn't do SRT but uses some body-based techniques) is that I made a point of asking her--several times at the beginning--to interrupt me during the session and have me check in to my body and to bring awareness to the momemt. I do this all the time with my clients so I wanted it with my own therapy.(I wrote a bit about it here: Counseling and Resistance)
This really helps as it gives me pause to reflect. I also happen to believe that it's an effective way to change emotional patterns.
That's great that you process after the session. I should do that too. I imagine it would reinforce whatever I got from it.
You had asked about processing ideas. I imagine if you get your body into a more relaxed state immediately after your session like with a hot bath, it would help you to process deeper. I'd try to get into the "feeling state" of the session (i.e. shifting into right brain).
Take care,
