Donnajean,
It is extremely normal for your husband to be fatigued and to sleep the day away after finishing radiation treatment. As I and others wrote in response to Kelly's questions in the topic below this one...it takes a long time to heal from radiation treatment. After 6 weeks of radiation I felt the worst that I felt in my entire diagnosis and treatment. Furthermore I have been unable to eat since 3 weeks into radiation and can only eat liquids 3 months after radiation! Read the other topic about the PEG...it is not a bad thing. It has allowed me to keep my weight up, and consequently has given me energy and helped me to heal.
Please be patient, things reach their low point after radiation ends, and gradually get better. Please reconsider the PEG and reread the posts in the topic below where you also posted.

Best of luck,
Danny G.
