As I said before, Good Luck.
When I was in chemo in 1991 a nurse at the oncologist's office said whe would rather work there than a general practitioners office as the patients didnt complain as much.
When I came out of remission in 2005 (non_Hodgkins lymphoma) I went from averaging 15 mph for Tour de Phoenix in April (75 miles) to barely being able to average that for 20 miles in June and July. I kept riding since it gave me something to hold on to. When the doctor started treatment (rituxan) in early August, he said I would feel better almost immediately. That was right; I was riding with the club again (50+ miles on Sat morning, 15 mph ave) by early September.
