My T doesn't have a couch, but I lie down on my chair as much as I can, plus I rarely look at him. I used to sit up straight, but I can't feel any emotions when doing that, I just turn them off. My T is actually kind of bothered by the fact that I don't sit up straight, but he doesn't mind too much. I like it more this way because I can feel what I am feeling, instead of just shutting down. You can always try for a session or two and then go back if you don't like it, that might be an idea?
