LLoyd, when I was going through radiation and chemotherapy,it wasn't pleasant. I found my energy would really take a nosedive during each course of treatment.
I tried to work with the process mentally, to help by visualizing this medicine coursing through my body and aggressively attacking each cancer cell it encountered. I think it did help; I've been cancer free since 1977. I'll be thinking of you, and including you in my meditations.
Keep fighting the good fight.
