Hi Nancy,
You are so early in your recovery so give yourself a big hug, you are doing great!! Sleep patterns get disturbed with brain surgery, it happens alot, not to be negative but I am 4 years post surgery and I rarely sleep through the night unless I take a sleeping pill. Do you have an i pod or MP3 player? They are great little inventions. I listen to music or books at night on an ipod to fall asleep and it works great. That way the light is off and my eyes don't get over tired. If you have an MP3 player you can download books from the library, you mentioned you read alot so thought this would help. Hang in there Nancy, this is a slow, tricky recovery and it takes time,
Ruthie
