Hi Dai
Thankyou so much for taking the time to reply to my post, you don't know how much better I feel just reading this , to hear that it is quite normal for him to feel the way he has.
On another plus side my Dad has been taken off all his morphine, so something must be working as he was in a lot of pain before his treatment started.
We live near Milton Keynes and he is being treated at the local hospital which has a Macmillan unit.
Thanks again
Viv
