Hi Linda,
For background, last fall (06) I went through 6+ weeks of IMRT's to both sides of my neck, along with weekly chemo with Cisplaten and Erbitux (7 total treatments). I also had daily Ethyol shots.
I had a great deal of trouble eating fairly soon. My wife was making all sorts of things for me to try, but I just couldn't stand eating them - and wouldn't. So I finally made up a simple daily diet: 3 meals a day, each consisting of 2 Boost Plus (360 cal. each), an egg-beater omlet with cheese and sometimes ham, and tea with honey. About 2700 calories per day. I took less than 1 tsp. per meal of a throat numbing medicine my dentist made for me which helped when eating the eggs. With this meal, I lost very little weight and avoided a feeding tube.
So my suggestion is to try to find a very, very simple diet that has enough calories for maintaining weight. As with other things, it's a trial and error process - only Todd knows what works for him, so it's important for him to communicate what is not working and be willing to try other things to find an acceptable solution. I had a number of side effects, and the treatment for each one involved trying more than one medicine.
Regarding nausea, the first pills I tried (promethazine) did not work very well, and I ended up on Zofran, which was acceptable.
Best wishes and good luck.
Chris
