Lucy,
I am sorry to hear of your long ordeal. It is interesting for me to read these stories because the symptoms do seem to be similar. You seem to be suffering from a lack of mental stamina and need the naps to regain strength. I see this in my son and worry if he does not get adequate rest. This seems to be the one thing that makes him sharpest. You have somehow figured this out on your own. There is so much still to understand with these tbi's and listening to the individuals who are suffering and dealing with the effects each day is helpful. I just wish the neurologist would spend more time listening and understanding. Hang in there, maybe you are still getting a little better each year.
Nancy
