Before doing that, I would first experiment with just how volatile those insights really are.

For example, put a bowl in front of me and a pile of small rocks, and every time I have what feels like a clever/creative/insightful thought put a rock in the bowl, then forget about it. Afterwards, try to remember what my insights were, and compare the total to see how many I forgot.

If it turns out that I can remember them later, then I don't need pads and etc.

(This was, incidentally, a glorious moment in my recovery, when my memory improved to the point that I didn't have to rehearse things constantly in order to stand a chance of remembering them when I needed them, but could instead let them go in the confidence that I could get them back later.)
