David, I would suggest that much of your being tired and weak is due to the IMRT. John had 30 rad txs and they wiped him out by the end. He spent many hours doing nothing but sleeping for the next month. After that, he would work in the morning and rest in the afternoon. You could try a comprimise with the liquids vs. food arguement. Set a base of 2000 cals in liquid nutrition and try to add another 800 with solids. Cheese, cream soups with veggies, pastas with rich sauces, baked potaotes with sour cream and cheese, any meats you can eat will get those calories up. As long as you continue to gain your weight back, experiment. But don't discount what the IMRT did to your system. It sound like you are doing pretty well. Amy
