Hi there! Sorry you're going through this, a lot of us here have done the radiation thing.. NOT FUN, but doable, it's a day by day chore and generally doesn't get too bad until week three. Will he want to come home on Weekends...? Probably up until the last few weeks. I drove myself to and from rads, everyday up until the end... This was up to a 45 minute drive each way, and at least a 2 hour time investment. Then I would crash. Im thinking he would probably just want to be home to be normal. They will probably peg him for nutrition, but right now try upping his protein intake. A dietitian can tell you how much he needs for healing. I managed to maintain the right amount guzzling ensure, and adding vegetarian protein powder to it. This will help with the surgical healing too. Neck dissections aren't too bad... It does mess with your shoulder and neck of course but physio should help at some point... Even passive physio. The teeth will heal. I know it's hard to watch just take your cues from him, and dig your heals in when it comes to eating. hugs and welcome.
