I had a similar experience after recieving a concussion this summer. My memory was shot, I had to write everything down constantly. Basically it forced me to become more organized and really simplify my lifestyle. I was really close to getting burned out. It's been a rough trip, but I'm starting to get a good foundation built again. Learning to cut down my projects and not working like a dog has helped out immensely. I would not like to experience that handicap again, as I'm still often struggling with the effects.
