Hi Anne,
Glad to hear this week wasn't too bad. Just something I notoced you said at the beginnig, that your sknin was a bit sore. It will probably get much worse, and make sure you moisturise the neck area. We were prescribed generic aqueous cream. I had a giant pot and used to lay it very thickly 1/4 inch thick on his neck and we had a thin cotton scarf given by the nurses and wrap his neck in it. I did that at night before bed and after the radiation (we had to rinse it off before the radiation). It worked miracles, his skin didn't blister. It did get very smelly but one day in the shower the moisturised dead layer of smelly skin fell off and there was new link skin underneath. So moisturise a lot.
As for the constipation Martin says it feels like he gives birth to an arm but he has been prescrived Latilose and it lubricates and helps, he says.
Good luck.
Cecilia
