...is not just in my head.
Finding the right word eludes me. Being consistently coherent is an unrealistic goal. My short term memory is more or less non-existent.
My brain has slowed right down.
I have lost about a hundred consecutive Scrabble games (I play online at www.pixiepit.co.uk/scrabble, a site worth visiting for its amusement value).
I really hope the damage isn't permanent.
