OP here.

I'm sorry but I quit on the 2nd day. The first day I spent a full 30 minutes trying to do the exercise. On the 2nd day I couldn't continue because there was just too much room for doubt.

The exercise is vague enough that I could tell myself - "maybe I'm doing the visualization wrong, am I supposed to imagine a stream of vapor coursing through my entire body at the same time, or should it be a single stream of vapor that starts in my arm and works its way through all of my limbs and then go up by torso to my head and back down?"

Put that together with the fact that I was still feeling nothing and that there was a specific exercise for something else I wanted to practice that isn't even remotely vague, and I just couldn't hold on to the possibility that after 3 and a half hours of doing an exercise that I'm not even sure I'm doing correctly that I'd finally get a result.

Maybe this thread and your advice will serve someone else, but there aren't really any markers for improvement in this thing, I just felt like I was wasting time like with everything else I tried.
