I don't have twice a week appointments on any sort of regular basis. With my former T, I think I had twice a week appointments twice. I didn't plan the sessions but then again, I don't really plan them with once a week. With my new T, I'm only having sessions every other week and its really hard to maintain any sort of connection or continuity but I've only seen her twice so I don't know if that is part of it. The two times I did have twice a week sessions it was because I was really traumatized at the time and really in a bad space. I don't think I had the ability to plan anyway, my head wasn't in a good space. I think though that you could try planning some topics for the first appointment and some topics for the second and see how it goes.
