Cherry, one of the side effects of radiation is fatigue. It also seems to be cumulative. In other words, the more radiation he gets, the more tired he will be. Our RO told us that the radiation treatment should not be interrupted -- a weekend break is fine -- because it allows the cancer to repopulate. John had to do two sessions of radiation in a day during the Christmas and New Year breaks with six hours in between the two sessions. They may ask Larry to do that too, so be prepared.
