John, The 'visualisations' that Gary suggested can be very, very helpful in boosting the body's immune system.....and all the good wishes & prayers from your 'comrades' can only help as well! Your wonderful sense of HUMOUR may be tested .....but I'm sure you will reach the end of the treatments successfully....and move on to .... (maybe)... bigger & better things. I,too,.... will be thinking of & praying for you. Joe G. from Sotland
