I am a 'world champion at sleeping'. I slept mega portions of the day and night during radiation treatments partly out of boredom and partly because I was freezing. Unless you are having bad dreams, 'sleeping though it', reduces the amount of calories you are burning. HOWEVER, when you are awake, you need to go out and take a walk around the block to keep those other muscles working and smell the fresh air, and do whatever normal stuff you can do. Yes, fatigue from both drugs and treatment is common and lots of sleep may result. Remember to keep hydrated and get enough calories. Keep swallowing regardless of whether you have a peg or not. He can do this.

Take care,
Eileen
