Thanks Jo1234,
Some very useful advice, which i will heed. Its funny, I was just reading about Professor Boyages' book last night. I will pick up a copy, and might be lucky enough to get the good Professor to sign for me.
I was not aware of the tiredness issues, so thanks for the heads-up. I am not a very good sleeper at the best of times, so it will be interesting to see how I go. I have recently retired from work, so I should have some time to Nanna nap.
I hope you are doing well now after your treatment, and continue to do so.
Again, thankyou for your input,
