Hi Doug,
I went through treatments earlier this year. Eat as much as you can of what ever you can for as long as you can because you will not regret it.

Take good care of your skin during radiation, it can make a huge difference. There's a regiment that I used that I had great success with. You do need to lubricate your skin right after every treatment and continue several times a day.

It's good you have a port, it'll help so much.

Do you have an appointment calendar on your phone that you and your wife can share? Yes, it's going to get super rough but you can do it. Your wife can be a great help.

Complain about whatever you like, it's okay. Come here and rant if you need to because during those bad days, you might need to. There's also all sorts of suggestions we can give you for all sorts of troubles. Keep us informed as to what's happening
