Hi! I had my surgery 7 years ago this month and also have a Terrible memory and have "adjusted" to the situation at hand with constant repetition and written instructions to learn something new. Repetition seems to be the key for me as well as doing it hands on myself. If I have the opportunity to do it myself a few times I am much more likely to retain the information (although not always by any means).

Hope this helps some. I would be interested in any information myself.
