Thanks peacetrain.  
I now have my 'yesterday' head on.  Been doing Newcastle for two and a half weeks.  Weight falling, and I have appointment for HbA1c results and review tomorrow. I am going to rethink the whole food thing this week, as although I have had a great deal of success in the past on Newcastle diet, I am finding it tedious at the moment. I have cravings for some good protein, so maybe the low carb way is what I need.
I have been seeing a very good physio who has given me some manageable exercises, and suggested a Pilates dvd.  I have the dvd, it is good, but I am hearing impaired and the instructor has an Australian accent which is difficult to understand particularly as there is music in the background.  I am trying to read subtitles and follow the programme at the same time.  Not easy as I am also short sighted, but it is amusing me.
I have done tai chi in the past, and would recommend it as a calming, and strengthening exercise.  Unfortunately not able to do that anymore due to impairments.
I have always felt most comfortable in water.  I can move without pain, and almost feel as though I am able bodied again.  Getting to the pool is difficult and the council is closing many of the pools where I live.  I am slowly building up to, hopefully, the level of fitness through water exercise that I had a year or so ago.  It will be a long struggle due to having two major operations recently, but I will find a way, or make a way.
Thank you for helpful suggestions.
