Concentration Levels begining to come back

I have been finding it quite difficult to concentrate since the Operations either because of the General Anaesthetic or because of thinking about the disease whether consciously or subconsciously which meant that I was having real difficulty concentrating for long periods of time. today I feel that I have finally come out of that, albeit in a small way. I have actually spent most of the day in a productive manner and produced tangible things. Wow!
