Hello Yan
My appointment time was early evening. Sometimes I felt ill after the radiation and was able to go to bed and often sleep through the worst of the after-effects.
Another cancer patient advised me to do this before I began and I am pleased I was able to follow her advice as it gave me the mornings when I felt a little better.
I didn't have chemo, so that wasn't a consideration.
Wishing you well, love from Helen
