Stef,

It IS daunting to be told that you will have two radiation treatments in a day. My husband's treatments spanned the Christmas and New Year holidays and so we got the double-header a few times. You will be given 8 hours between the two sessions. You may want to think about whether you want to drive home after the first session and then drive back or if there is a treatment center at the hospital where you can rest between the two sessions. It makes the patient quite tired at the end of the day but the side effects are not going to be doubled noticeably. It's just annoying to have to be there almost like first thing in the morning and then return in the late afternoon. Like you said, all the side effects do seem to start all at once and it seems that the fatigue is the worst.
